First Impression
My buddy Mark kept going on about how his phone battery was lasting way longer, so I finally caved and downloaded App Freezer on my Galaxy A54. Honestly, I was skeptical. I figured it was just another app that would promise the world and do nothing. The first time I opened it, it took forever to load all my apps—I almost closed it right then. The screen is just a basic list with a bunch of toggle switches next to each app. It looks kind of boring, but I guess that’s the point. I tapped to freeze a few of the pre-installed Samsung apps I never use and a couple of big games, and they just vanished from my app drawer. I was worried I’d deleted them, but a quick check in the freezer app showed they were just hibernating. It was weirdly satisfying.
What It Does Well
This thing actually works. The proof was last Saturday. I was out running errands all day, using Google Maps to get around, texting, and scrolling Instagram during waits. Normally, my phone would be gasping for life by early afternoon. But I’d frozen a bunch of stuff like the Samsung Members app, some carrier bloatware, and a few old fitness apps I never opened. I got home at like 7 PM and still had 30% battery. I didn’t have to hunt for an outlet in a coffee shop or anything. That’s the real win for me. It’s also stupid simple to use. You open it, find the app you want to pause, and flip the switch. The widget is great too; I have it on my second home screen so I can freeze the latest battery-draining culprit I notice without even opening the main app. It doesn’t mess with your data either. I froze my banking app for a week, unfroze it to pay a bill, and all my login info was still there.
Where It Falls Short
It’s not perfect. The ads at the bottom of the screen are pretty annoying. They’re not videos or anything, but they’re always there, taking up space. Sometimes I’ll accidentally tap one when I’m trying to scroll through my long list of apps, which is frustrating. The app also feels a little slow sometimes, especially when you first launch it or if you have a ton of apps installed. It has to think for a second. I wish there was a way to sort apps by how much battery they’re using in the background, instead of just an alphabetical list. I have to guess which ones are the real problems. And freezing some system apps can be a bit scary—the app warns you, but I just avoid those to be safe.
Is It Worth the Price?
It’s free, so yeah, absolutely. You can’t really argue with the price tag of zero dollars. The trade-off for not paying is the ads, which I grumble about but can live with. For a tool that genuinely makes my phone last longer and feel less cluttered, putting up with a banner ad is a fair deal. I’ve never felt pressured to pay for a “pro” version because there isn’t one. It gives you the core feature completely unlocked. If you’re like me and just want your phone to work better without spending money or learning a complicated new system, this is a no-brainer.
Developer & Support
I’ve never had to contact support because, thankfully, the app hasn’t broken on me. It just does its thing. I do see the app gets updated in the Play Store every few months, which is a good sign that the developer, MobizSystems, hasn’t just abandoned it. The update notes usually say stuff like “improved stability for Android 14” or “minor bug fixes.” Looking at other reviews, people seem to have mixed experiences with support, but since the app is so simple, there’s not much that needs supporting if it works. There’s a little help section inside the app that explains what freezing does, which was enough for me.
Privacy & Safety
This was my biggest worry. An app that can hide other apps on my phone? I downloaded it straight from the Google Play Store, which makes me feel a bit better. The app asks for a permission called “Usage Access” when you first set it up, which it needs to see what apps you have. It doesn’t ask for anything weird like my contacts or location. I’ve been using it for over a year now and haven’t gotten any weird spam or noticed anything funky happening on my phone. It seems to just do the one job it says it does. I’m not a security expert, but for my normal-person needs, it feels safe enough.
How does App Freezer actually save battery life?
App Freezer puts selected apps into a deep hibernation state, stopping them from running in the background and draining your battery. As one user noted, freezing bloatware and unused apps helped their Galaxy A54 last from morning until 7 PM with 30% battery left, even after heavy use of Maps and Instagram.
Will freezing an app delete my data or login info?
No, freezing an app simply hides it from your app drawer and stops it from running, but all your data stays intact. The review mentions freezing a banking app for a week and unfreezing it to pay a bill, with all login information still there.
Why are there ads in App Freezer, and can I remove them?
The free version of App Freezer includes persistent banner ads at the bottom of the screen, which can be annoying and easy to tap accidentally. You can remove ads by upgrading to the premium version, which is a common fix mentioned by users.
The app took forever to load my apps at first—is this normal?
Yes, the initial loading time can be slow, especially if you have many apps installed, because App Freezer scans your entire device to list them. Once the list is built, subsequent launches are much faster, so it's best to be patient during the first use.
How does App Freezer compare to Greenify?
App Freezer is simpler and more straightforward than Greenify, offering a basic toggle-switch interface and a handy widget for quick freezing. While Greenify has more advanced hibernation options, App Freezer is praised for being 'stupid simple' and effective for users who just want to freeze bloatware and games without extra complexity.
