Emoji Battery & Status Bar · Taka Group - Maxlabs Personalization Tools

# A battery icon emoji swap app from an app factory hit 100k installs in two months: it's the 20th, not the 1nd

**What it is** A personalization tool that swaps the battery icon in the Android status bar for emoji and stickers. It makes money from ads and in-app subscriptions.

**Why it took off** It hasn't really taken off. The category demand has always been there (iOS can't do this, so people can only install Android apps). It gets traffic from its parent company's older apps and from category keyword searches. After a step up in Oct 7, it settled at two or three thousand installs a day.

**C** **How you could approach it** Don't copy it directly. If you already have personalization apps that can cross-promote each other, you could build a version with a new hook at low cost (battery-linked desktop pets, holiday or IP stickers, language switching), and get users with TikTok demo videos plus long-tail store keywords.

Grade C: the category demand is real and still growing, but by 2026 there were more than twenty apps with the same name, and the leader is two orders of magnitude ahead. This one is itself a copycat that got going through factory distribution. You can learn the app-factory playbook and "deduplicating the top charts", but starting from scratch and following it isn't worth it. Few people know about it yet

Data 2026-10-29 → 2026-11-07 (10 days, 10 observations)

In Sep 5, a company registered in Hong Kong with a Vietnamese phone area code listed "Emoji Battery & Status Bar" on Google Play. It swaps the battery icon in the top-right corner of an Android phone for a cat, a pizza, or a smiley face. Two months later it had 102k installs and was still on the "personalization" Top Grossing charts in more than a dozen countries. It looks like a new product taking off. Looking closer, it's a spot in an already crowded category, filled by an app factory with 145M cumulative installs. This piece covers why people keep installing this category, where the 100k came from, what those "multi-country Top Grossing" rankings mean, and whether you should enter.

### An app that turns your battery into a meme sticker

The store page opens with "Same battery icon every day, bored?" You pick a set of emoji (food, animals, hearts, plus seasonal Halloween and Christmas sets), grant an "accessibility service" permission, and it lays its own icon over the status bar. When the phone charges, the sticker changes with the battery level. The store page has a section explaining why it needs accessibility permission: "Used only to display the custom battery icon and status bar overlay. Does not read passwords or private messages."

It has few reviews on Google Play. One user in Oct 3 wrote: "This app is so cool! My sister uses it every day, her wallpaper looks way better than mine 😏👍" Another review from Sep 26 says only: "Free trial for a week? No thanks!" Besides ads, it also sells subscriptions and in-app purchases, listed at $9.99 to $39.99 each.

The demand is real. iOS doesn't allow changing the system battery icon, so iPhone users can only watch the trend on TikTok. "Emoji battery" has been a common topic since 2023. In March 2023, one demo video got 8.45M views. People who want this effect have to install an Android app, and the people who buy these tend to be students and young people who care how their phone looks, not whether it's useful.

### Its 100k installs came in one jump

Estimated from Google Play install counts (AppstoreSpy historical data plus daily observations from October onward):

- In the first month after launch on Sep 5, it got about 100 installs a day, roughly 29 total by Sep 2,000.

- From Sep 30 to Oct 4, daily installs rose to 500–1,100.

- **On Oct 7, installs rose by about 13k in one day** , and the next day added another 2,700.

- After that it stayed flat at 2,000–4,000 a day: about 27k in Oct 74, 6 in Nov 102,407, and 7k new in the last 28 days.

A slow start, then one step up, then a flat line. That doesn't look like word of mouth from a single video. It looks more like someone opened a traffic valve: paid ads, cross-promotion from older apps, or a store featuring spot. I found no direct evidence for which one, so this is an inference . It has 199 ratings averaging 4.55 stars, but the counts for 1-star and 4-star ratings have stayed the same, and there are none at 2 or 3 stars. That's an odd shape. It could be an approximation Google shows for small samples, or it could be prompted positive reviews. I can't confirm which.

### Who's behind it: a personalization-tool factory with 145M installs

The developer is listed as "Taka Group - Maxlabs Personalization Tools." The store lists MaxLabs Company Limited at Central, Hong Kong, with a contact phone starting +84 (Vietnam). Parent company TAKA Mobile was founded in 2019, and the team photos on its website are from Thailand and Vietnam.

Under the same developer account is a whole row of apps for "re-skinning" phones: Neon LED Keyboard with 73.2M installs, Rolling Icon 17.6M, Edge Lighting 10.9M, ThemeApp 9.55M, roughly 145M installs across the group. The users of these apps and of the emoji battery app are almost the same people. The usual factory playbook is for the old apps to feed traffic to new ones through interstitial ads and cross-promo placements, so a new app gets installs on day one and plugs straight into existing ad and subscription monetization inferred, indirect evidence .

Its chart presence backs this up. The best free personalization ranking is #33 in Thailand, followed by the Philippines, Indonesia, Malaysia and Vietnam, which are the team's home markets and cheap-traffic markets. The title uses the category search term "Emoji Battery & Status Bar" directly, and the description is stuffed with battery icon customize, status bar customization and charging icon, so store search is fully covered.

### "Top grossing in a dozen-plus countries" is one chart

The most impressive number for this app is that it appears on the personalization Top Grossing charts in Vietnam, Hong Kong, the Philippines, Nigeria, Turkey, Saudi Arabia, South Africa, Poland, Malaysia, Thailand, the UAE, the Netherlands, Mexico and Singapore, ranking 75–79 in each.

Nov 6: when you look at these countries' personalization Top Grossing charts side by side, the top 5 in Singapore, Poland, the Netherlands, Turkey, the UAE, Mexico, Vietnam and Hong Kong are identical: Zedge, Niagara, Facer, Smart Launcher, Cleanup. In other words, Google Play uses **the same global aggregate chart** for these small-country category rankings. "Top grossing in 14 countries" is really just one signal: #79 on the global personalization Top Grossing chart. On that same chart, its sister app Rolling Icon is #22, ThemeApp #40, and Edge Lighting #69.

On revenue, a third-party estimate (AppGazers) puts each app under this developer account at under $5,000 a month in Play in-app purchases, with the account totaling $0–70k a month, mostly from ads.

If you're hunting for opportunities in Google Play charts, remember this trap: **when a small country's category Top Grossing chart shows multiple countries, deduplicate before drawing conclusions.**

### Who's competing with it: at least a dozen ahead of it

Pulling up the emoji battery apps launched in 2026 with the name in the title gives more than twenty. It ranks roughly #20 among them, two orders of magnitude behind the leaders. The main ones (Google Play installs, 11-06):

| Product | Developer | Launched | Installs | New in the last 7 days |
|---|---|---|---|---|
| Emoji Battery Icon Customize | New Widget Co. | 2026-04-22 | 15.6M | 376k |
| Emoji Battery Icon Customize | ZAppsolution | 2026-03-25 | 12.7M | 404k |
| Emoji Battery: Status Bar | HoangSi | 2026-06-09 | 3.9M | — |
| Emoji Battery & Shimeji Pets | ZAppsolution | 2026-07-17 | 3.56M | 266k |
| Emoji Battery & Shimeji Pet | Tools for Everyday | 2026-06-17 | 3.39M | — |
| Emoji Battery: Icons & Pets | SHINK | 2026-08-22 | 2.04M | — |
| Emoji Battery: Status Bar Icon | TRUNGHIEUCOM | 2026-08-14 | 1.42M | 143k |
| Battery Emoji Buddies | STARVIA | 2026-09-10 | 780k | 188k |
| **Emoji Battery & Status Bar** | **Maxlabs** | **2026-09-05** | **100k** | **28k** |

Three things stand out:

1. **Demand is still rising.** The top two have been out seven or eight months and each still adds around 400k a week.

2. **The category is moving toward desktop pets.** ZAppsolution, Tools for Everyday and SHINK have all shipped versions with Shimeji desktop pets (little characters that walk around the screen), and one of them has several million installs. This app doesn't have one.

3. **Late entrants can still move fast.** STARVIA launched 5 days later and now adds 6–7 times as many installs per week. Entering at the same time, a new hook or better creatives can make an order-of-magnitude difference.

Lutech (9-11.3M), randa (9-25), Growly (10-13), 368 Phuc Minh (10-21.1M) and OMG! Bros (10-29) have launched after it, and the copycats haven't stopped. Adjacent categories are big too: charging animation apps run 1M to 30M installs each, and dynamicSpot, a Dynamic Island-style app, has 14.7M.

### Where users come from and where the money comes from

- **Store search** : confirmed. The title is the category keyword, and it ranks on the Southeast Asian personalization free chart.

- **Cross-promo and traffic swaps from older apps** : no direct evidence, but the step-up in Oct 7 followed by a plateau, along with the group's other similar apps, both point here inferred .

- **Paid acquisition** : not found in the public Meta and Google ad libraries, but that doesn't prove it isn't spending.

- **TikTok** : category videos routinely reach millions of views, but the ones being pushed are competitors. A US mom creator posted in Nov 5 that "the app in the video is Emoji Battery," but there are too many apps with that name to tell which one it was.

- **Money** : mainly ads, plus a subscription with a one-week free trial and $9.99–39.99 in-app purchases.

No media coverage, and no relevant discussion on X in the past two months. Revenue isn't public. Few people know about it, but that doesn't mean there's an opening, because it's a copycat itself.

### If it were you

**Bottom line:** copying this app makes no sense, since it's already the #20 one. Demand for emoji battery apps is still rising and copycats keep coming, but it's a red ocean. What's worth learning is the app-factory playbook, not this app.

**Who it suits:** small teams that already have a stack of Android personalization, wallpaper, keyboard or theme apps that can feed each other users and monetize with existing ads. For you it's a low-cost fill-in: two or three weeks to build, plugged into an existing user base, and capturing the category's leftover demand.

**Who it doesn't suit:** indie devs starting from zero with no older apps to cross-promote and no plans to buy installs. You'd land behind twenty-plus apps with the same name, with no shot at store search. These apps also rely on accessibility services for their overlays, and Google Play is tightening review of that permission, so new accounts face a higher risk of rejection or removal.

**If you do build one, how:**

- Don't build "yet another emoji battery." Build what the others left out. Combining battery and desktop pets has already been shown to drive installs, so take one more step in that direction: a pet that reacts to your battery level, holiday-limited editions, or a sticker pack with a recognizable IP style.

- Change the audience or the language: the current leaders are concentrated in English, Spanish and Southeast Asian markets, and few store listings and screenshots have been localized into Japanese, Korean, Portuguese or Arabic inferred, not verified one by one .

- Copy the factory's monetization: ads, a weekly subscription with a trial, and a high-priced one-time in-app purchase.

**How to get users:** target long-tail category keywords in store search. On TikTok, demo videos of "making your phone look good" get views naturally, so make a 15-second clip of "the pet changes face while charging," post it yourself or find small creators. If you have older apps, start with cross-promos.

**When to move:** the category leaders still add 400k a week, so demand is still high. The window will be mostly closed once the leaders' weekly adds drop below 100k, or if Google Play tightens review of accessibility permissions. At the current copycat pace, the time left for new entrants is measured in months, not years estimate .

**What would show this read is wrong:** if over the next month or two, an emoji battery or desktop-pet app with no factory backing, starting from zero, breaks past several hundred thousand installs on TikTok content alone, the category is more open to newcomers than this analysis suggests, and it would be worth entering.

Where users come from

- Inferred **Parent company cross-promotion / traffic swaps** : the same account has personalization apps like Neon LED Keyboard (73.2M), Rolling Icon (17.6M), and ThemeApp (9.55M), with highly overlapping users. 10-07 +13k in a single day, then a plateau

- Inferred **Paid acquisition** : the growth curve is a step plus a plateau. Neither Meta's nor Google's ad library tracked its package name (not being on the list doesn't mean it wasn't spending)

- **Verified** **Store search / ASO** : the title and description use the category terms directly: Emoji Battery, Status Bar, battery icon customize. Rankings are concentrated in Thailand, the Philippines, Indonesia and other Southeast Asian personalization free charts

- Inferred **TikTok creators** : there are many category videos (millions of views), but they promote competitors. It can't be confirmed which Emoji Battery app @adhdancemom 11-05 was talking about

## Emoji Battery & Status Bar (hk.maxlabs.emoji.battery) research report

Research date: 2026-11-06. Channel: Google Play. Developer: Taka Group - Maxlabs Personalization Tools (maxlabs.hk, a Hong Kong shell company; behind it is the Vietnam/Thailand team TAKA Mobile).

### Bottom line

It never really "broke out." This is a copycat launched very late into the emoji battery icon category, which has been crowded for 2026 years, from an app factory with 145M cumulative installs that makes personalization tools. It has 100k installs and ranks outside the top twenty in its category. The "14 countries in Top Grossing" seen at first is one ranking (#79) on the Play personalization category's shared global aggregate chart. It can't count as 14 independent monetization signals. What lets it grow is the parent company's distribution capability (old apps' traffic, paid acquisition, store optimization/ASO), not the product itself.

### 1. Data (our googleplay library)

- Release date: 2026-09-05 (app.released_store). Version 1.1.3, last updated 2026-10-16. Ad-supported (ad_supported = True), in-app purchases $9.99–$39.99 each.

- Install curve (app_day_ext, AppstoreSpy estimates; from 10-29 onward is our own collection):
    - 9-17:420; 9-29:2,018. About 100 installs a day in the first month, mostly organic.
    - From 9-30 to 10-04 it rose to 500–1,100 a day (10-04 cumulative 5,757).
    - **On 10-07 about +13,232 in a day** (5,815 → 19,047), then +10-08 again on 2,713.
    - After that it settled at about 2,000–4,000:10-27 a day, which is 73,905,11-06 102,407.
    - 7 days of new installs 28,408 (app_profile.installs_gain_7d).

- Rating: 11-06 across 199 reviews, 4.55 points. 10-29 is 148, adding 2–9 a day. The histogram [18,0,0,18,162] has 1-star and 4-star counts always identical, and 2-star and 3-star both at 0, an odd shape. Possibly Google's approximate figures on a small sample, or review prompting; not verified.

- Charts (chart_rank, 10-29 to 11-06):
    - Free chart: the personalization category peaks at #33 in Thailand (latest #60), ranks 58–129 in the Philippines, 72–111 in Indonesia, and between 87–189 in Malaysia, Vietnam, Turkey and Saudi Arabia.
    - Top Grossing: the personalization category ranks 75–79 in vn/hk/ng/ph/za/th/sa/pl/my/mx/ae/ar/sg/tr/nl. 11-06 checked: the top 5 of the personalization Top Grossing charts in sg, pl, nl, tr, ae, mx, vn and hk are identical (Zedge, Niagara, Facer, Smart Launcher, Cleanup), which means these storefronts use **the same global aggregate chart** . So "top grossing in more than a dozen countries" really just means #79 on the global personalization Top Grossing chart. On that same chart, its sister app Rolling Icon ranks #22, Fluid Magic #36, ThemeApp #40, Neon LED Keyboard #48, and Edge Lighting #69.

- Third-party estimate: AppGazers puts each app under the Maxlabs Personalization developer account at under $5K/month in Play in-app purchase revenue, with the account totaling $0–70K/month (https://appgazers.com/reports/developers/android-6308639599032324688). Revenue comes mainly from ads.

### 2. Competitors (same job: replacing the Android status bar battery icon / adding emoji stickers, mostly implemented with accessibility-service overlays)

On Google Play, apps with "emoji battery" in the name that launched in 2026 number 20+; the main ones are listed below (installs and 7-day gains are 11-06 data):

| Product | Developer | Launched | Installs | 7-day gain |
|---|---|---|---|---|
| Emoji Battery Icon Customize | New Widget Co. | 2026-04-22 | 15.6M | 376k |
| Emoji Battery Icon Customize | ZAppsolution | 2026-03-25 | 12.7M (479k ratings) | 404k; Spain personalization Top Free #1 |
| Emoji Battery: Status Bar | HoangSi | 2026-06-09 | 3.9M | — |
| Emoji Battery & Shimeji Pets | ZAppsolution | 2026-07-17 | 3.56M | 266k |
| Emoji Battery & Shimeji Pet | Tools for Everyday | 2026-06-17 | 3.39M | — |
| Emoji Battery Widget & Icons | Tools for Everyday | 2026-06-23 | 2.89M | — |
| Emoji Battery: Icons & Pets | SHINK | 2026-08-22 | 2.04M | — |
| Themix: Emoji Battery Widget | ScreenSpark | 2025-11 | 1.59M | — |
| Emoji Battery: Status Bar Icon | TRUNGHIEUCOM | 2026-08-14 | 1.42M | 143k |
| Emoji Battery: DIY Status Bar | ImoDevel | 2026-08-10 | 830k | 110k |
| Battery Emoji Buddies | STARVIA | 2026-09-10 (5 days later than it) | 780k | 188k |

- Later launches include: Lutech (9-11.3M), 368 Phuc Minh (10-21.1M), randa (9-25), Growly (10-13), OMG! Bros (10-29), and others.

- Adjacent categories: charging animation (the Battery Charging Animation series, 1M to 30M installs each), Dynamic Island / Notch (dynamicSpot, 14.7M), Super Status Bar (Tom Bayley, 5.18M).

- Platform and iOS side: iOS doesn't let apps change the system battery icon, so the only options are widgets or lock-screen gimmicks. "Emoji battery" has been a common TikTok topic since 2023; for example, @greenwaremobile's 2023-03 video has 8.45M views.

- Takeaway: this category has been a red ocean for a long time. Among the 2026 emoji battery apps, it ranks roughly #20, two orders of magnitude behind the leaders.

### 3. Growth tactics

- **Parent-company matrix and distribution (inferred, indirect evidence)** : Under the same developer account are personalization apps such as Neon LED Keyboard (73.2M), Rolling Icon (17.6M), ThemeApp (9.55M), and Edge Lighting (10.9M). The whole Taka Group has about 145M installs on Google Play. These apps' users are exactly the emoji battery target audience, and cross-promotion and interstitial-ad traffic swaps between older apps are a standard playbook for this kind of factory. Also, after a single-day jump of +13k on 10-07, the app has held at 2,000–4,000 per day, which looks more like paid acquisition or cross-promotion than organic virality. Unverified.

- **Paid acquisition** : Our Meta and Google ad libraries have not tracked any Maxlabs/Taka package names (the Google ad library only reverse-looks up products on our list, so not being on the list doesn't mean they aren't advertising). The TikTok "emoji battery" videos with millions of views (@user4081107443555, @batteryicon) promote competitors, and nothing shows a link to Maxlabs.

- **Store search and ASO** : The title uses the category search term "Emoji Battery & Status Bar" directly, and the description is stuffed with keywords (battery icon customize, status bar customization, charging icon). Charts are concentrated in Thailand, the Philippines, Indonesia, Malaysia, and Vietnam, consistent with the team's location (Vietnam/Thailand) and low-cost traffic markets.

- **Creator content** : No Maxlabs account or sponsored video was found. TikTok creator @adhdancemom (19k followers, US) posted "The app shown is: Emoji Battery" in 11-05, but it can't be confirmed that it refers to this app (there are many apps with that name).

- **Media and X** : x-radar finds no "emoji battery" posts in the past 60 days; there is no press coverage and no public revenue figures.

### 4. Why it took off (for its scale)

1. Demand for the category has been validated and is still growing: the two leaders, ZAppsolution and New Widget, each added about 400k over 7 days, so demand persists and late entrants can still win a slice.

2. The parent company has a ready personalization user pool and a monetization system (ads + $9.99–39.99 in-app purchases). A new app can plug straight into traffic swaps and monetization, so the cost of making a copy is low.

3. The growth inflection was a single step-up on 10-07, followed by a plateau. It looks like paid acquisition or cross-promotion, not word of mouth.

4. The "14 national Top Grossing" cited in the recall scoring is an artifact of aggregate charts; actual monetization is not high (AppGazers estimates in-app purchases for a single app on the same account at < $5K/month).

### 5. Differentiation

No substantive differentiation. The features (emoji battery icons, status bar stickers, charging icons) and the name are category standards, and it lacks new selling points that rivals have already introduced, such as Shimeji desktop pets or Notch. Its only "difference" is that a large app factory stands behind it, so it succeeds on distribution and resources, not on product.

### 6. What to borrow

- The app factory playbook: once a category is validated on Google Play, ship copycats within 3–6 months from the same developer account, borrow the user pool of older apps through cross-promotion, use category keywords in titles for ASO, target Southeast Asia's low-cost traffic, and monetize through ads plus high-priced in-app purchases.

- A note on research method: the category Top Grossing charts for small countries on Play often reuse the same global aggregate chart, so deduplicate "charting in many countries" before drawing conclusions.

### 7. Uncertain

- No direct evidence was found on whether the jump on 10-07 came from paid acquisition, cross-promotion, or store featuring.

- We cannot verify how many people actually make in-app purchases.

- Unconfirmed whether the unusual shape of the rating histogram is Google's approximation or incentivized reviews.

- Unconfirmed whether the app in @adhdancemom's video is this one.
