It did not help, and was a total waist of storage. -Sage June ### 1/5 — Lock Screen *2022-04-28, version 1.4* People, Don't download unless u want a Lock Screen and all Lock Screen.Developers I need u to look at this cuz I want it to be 5 it’s a 4.4 but I hate it so much that it should be deleted from the App Store cuz u wasted my time and I hate this app so delete it or make use of it. People I don’t blame u if u feel the same. If u gave this app a 5 then ur a joke cuz be honest it doesn’t work. I’m being legit rn this app is trash ### 3/5 — Payed for permanent but *2022-04-23, version 1.4* Still see advertisements. Why? ### 1/5 — Won’t load *2022-04-14, version 1.4* After several times of trying and trying, the app wouldn’t load for me. I’ve waited for over 30 minutes for it to load and it just shown a white screen. I can’t really tell you anything about this app because it would NOT load. Hope you take this into consideration. Kind Regards, Wolfie ### 1/5 — Billy Bob *2022-01-02, version 1.4* This is junk I told it is junk you got put out junk more than you do anything else junk junk junk junk junk junk ### 1/5 — Ad free version still has ads. *2021-12-31, version 1.4* I paid $9.99 for a lifetime subscription to remove ads, but the ads are still there and the app does little to prolong battery life. Will be seeking a refund if the problem is not resolved. ### 1/5 — Beware *2021-12-25, version 1.4* I downloaded this app and now want to delete. Now I can’t delete this. It’s imbedded. If anyone knows how to delete let me know. ### 2/5 — problem.. *2021-12-24, version 1.4* hi! I think this is a great app, but my iPad has been recently saying “Not charging” I’ve been getting annoyed and I downloaded this app but it kept saying “Not charging” and it would go down so quickly. I tried cleaning out my charging hole where I plug the cord in (I searched it up why it always says “Not charging” and it said I had to do that) but it still did that, and now my little lightning bolt on the top right side of my screen percentage is flashing? It’s on 5% at the moment ### 3/5 — battery capacity *2021-12-21, version 1.4* battery capacity is real? ### 1/5 — lifetime purchase not received *2021-10-12, version 1.4* Paid A$14.99 but still see ads. Pls fix， restore purchase doesn't work. ### 1/5 — This app does not work it made me lose battery instead of gain it so *2021-09-19, version 1.4* utterly unacceptable and all these other reviews are fake ## Most critical reviews (10 lowest-rated) ### 1/5 — Remboursement demandé *2024-09-09* Après avoir payé pour une utilisation à vie, l’app me demande de payer, les pubs envahissent les écrans. La réinstallation de l’app n’a rien changé. Déçu ### 1/5 — Pro version doesn’t work *2024-09-05, version 1.4* So I paid 10 euros for upgrade to Pro, but even after restarting my phone the Pro version doesn’t seem to work. “Extend battery life” doesn’t work, it just requests me to upgrade again. I also keep seeing ads. iPhone SE 2022. I emailed support but no response. ### 1/5 — NO FUNCIONA *2023-11-30* No funciona en Ios 17 ### 1/5 — Does Not Wirk on my iPhone 11 with iOS17 *2023-11-06, version 1.4* All that comes up is the percent of my battery charged with the background of the ocean. There are no buttons or menu to tap. ### 1/5 — Lifetime Pro Features not activated after purchase *2023-02-18, version 1.4* I contacted the Developer but decided to just request a refund from Apple after seeing that other people had this same issue a year ago. I assume no work around bothered with in that time. ### 1/5 — Battery Thing *2022-11-26, version 1.4* Too complicated to deal with. I prefer ver. 1. ### 1/5 — Don't buy *2022-11-23, version 1.4* I upgraded this product 6 months ago in order to remove ads and get the better version. You guessed it. I still get ads and the upgrade never occurred! I've contacted support but all I receive is crickets. AVOID THIS APP ### 1/5 — Scam *2022-09-19, version 1.4* Bought the full version and nothing changed. Still get ads and still get prompted to upgrade to the full version. Tried restoring the purchase and it says “restore success”, but nothing changes. ### 1/5 — I paid lifetime and nothing changed *2022-08-08, version 1.4* I just paid 13$ for lifetime and nothing changed ? Did it mean I paid for nothing ? I didn’t even get the pro version. ### 1/5 — Spyware *2022-06-23, version 1.4* Any app that tries to access information on your iPad by getting into other apps has spyware attached this app should never ask for access to your photos in order to manage a battery. ## Most praised reviews (10 highest-rated) ### 5/5 — battery saver *2026-03-20, version 1.4* excellent work ### 5/5 — I love it💕 *2023-09-01, version 1.4* It works a lot I love it I recommend it to everyone who is looking at these reviews please download it!!!🥰💕 ### 5/5 — Best app ever *2023-09-01, version 1.4* Who ever is watching just download it’s the best freaking app ever recommend put on charger and ho on app it charges really FAST Then ever like even if you have a fast charger then it even makes it faster!!! ### 5/5 — Top *2023-08-17* Nutze ich seit Jahren und ist top! Der Kauf lohnt sich aber nicht da sich die „free“-Version von der Bezahlversion nicht unterscheidet. Die/das Werbebanner zum kaufen der App bleibt - Leider. ### 5/5 — Best game ever *2023-01-27, version 1.4* It dels copy’s and saves battery life.This app is very very useful.Thank you creator! ### 5/5 — How do you start it somone answer please ???? *2022-05-30, version 1.4* How do you start it somone answer please?????sksmksksksksksmmsmxkxksksksk ### 5/5 — Batter savery *2022-04-17, version 1.4* Battery save is good i deleted it and my battery went down by alot also im not a bot or joking ### 5/5 — Love this app *2022-03-02, version 1.4* Great app, well done guys ### 5/5 — THIS IS AMAZING *2021-09-05, version 1.4* when i installed this, i thought it would help me a bit but when I realised that it helped me a TON like my battery took forever to go to 0% so i REALLY recommend this. ### 5/5 — Simplicity is Genius *2021-04-19, version 1.3* This app gives you really effective tips on to saving your battery, it’s very simple and easy to understand, not only that but I love its feature in which you can clear out so much space, it will look for photos you can delete and tell you how much space you will save, before typing this review I cleared out 1.35 GB, it will also let you go through the pictures it chose so you can keep some of the photos you don’t want to delete, I think if you are looking for a storage saving app, this is the one, and when it comes to battery saving it’s not bad at all, still trying to figure out if it can actually slow it down and not just give tips but its still a brilliant app to have either way. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
