Review 1 by Hansen: Hey man. I have some good feedback for you. After you made some changes to your app my battery life is longer. I see a huge improvement, my battery has now power to a whole day even if I play games and do some other stuff. Before that my battery was drained an hour before I went to bed. Now I have about 10-30% when I go to sleep AND now it’s colder here in Denmark. Very cold. You know… batteries use more power when it’s cold so that’s a good thing, even if it’s colder my battery lasts longer.
Review 2 by dontbelive: Heey all ,,after i test this app on my mothers xperia x10 (2.3.4 custom rom) and m fathers lg 2x speed (4.0.4 stock pre-rooted rom) this apps works really great up to 1,5 – 2 days
My battery problem is gone since i use this app
(i dont like battery saving apps because they draining my battery more than.before but this is really.amazing).
This app works only with root this tweaks the kernel ,wireless etc.. for each mode

Review 3 by bratusm: I started in the evening, with fully charged battery, at 22.00. I checked battery status (%) next morning at 08.00
- without One Power Guard 2.2: 78%
- with One Power Guard 2.2: 97%
No need to say more… One Power Guard 2.2, at least for my phone, is working excellent!!!

Review 4 by neoyoli: Your scroll cache hack definitely And maybe the One Power Guard app by onexuan, it is really really good. I don’t know if it has anything to do with it, but since I installed it and set the CPU speed to min. 120MHz, max. 756MHz, the game lag with the oc kernel described in the Nameless thread lately is gone.
I’ll ask einstein.frat about it btw, maybe it helps to have a flawless oc kernel by default.

Review 7 by takumibunta: I found the second solution, which is using the ONE POWER GUARD. Now, the battery life IMPROVES EVEN MORE! Now when I wake up to check my device, a whole night sleep is just draining 2-3% the most!

Review 8 by roonie: I found a difference only after using for 1 week.. Before using one power guard , battery was draining with 10% an hour during night(even when i dont use also) (So if at night its full charge at 6.00am it will be 40% charge left)
After using one power guard for one week , battery backup increased with more than 50%…(So at night if its full charge at 6.00am it was above 80% like that)

Review 9 by Shawnki91: Install “One Power Guard” and use the “AI” mode. It does not affect radio use, but rather optimizes the CPU governor in order to save power depending on what you are using this for. With bluetooth turned on for at least 6 hours a day, email, txting, web browsing and some video, my streak last me throughout the whole day, and I usually have about 20%-25% left by the time i get home at night–try it out!

Review 10 by uluvali: Installing it now. I have been having horrible battery life recently. 2-3 hrs per battery with everything off (wifi, bluetooth, 3g, gps,etc…). I am currently looking at the battery usage screen. After 35m 31s, I have 59% battery left – (cell standby 39%,phone idle 31%, android system 17%, display 15%)
The screen is warm to the touch. I don’t think that I could have 3 batteries go bad simultaneous? I haven’t changed any settings recently. Im on the latest DSC 2.3. I did have a problem similar to this previously but it was a busybox upgrade that caused it. I downgraded and everything went back to normal.
I will let you know if “One Power Guard” solves my battery problem. Thanks

Review 12 by eddy0090: I started using one power guard and I believe it really works. Also I found that turning off Gps while not using apps that need it increases battery life by a lot.

Review 13 by akk29: I have been using an app called One Power Guard which does seem to improve battery life mainly during standby without any discernible decrease in performance. This app causes various system and kernel tweaks, Disabling data connections etc is well known to help improve battery life but I have also found a big difference by turing off Use Wireless networks in the Location and Security Settings.
A second battery with this ROM is recommended and I am very happy with the Mugen 1800mah battery.

Review 15 by takumibunta: For the battery drain issue, I used One Power Guard, which I tested before, it does reduce the power usage (Got a very good result during deep sleep, and daily usage… usually without using it, my battery drains at least 7% after whole night, while using it, my battery only drains about 3% the most!)

Review 16 by TheRedHunter: One power guard should be added too. Also you should check lighting browser, fastest browser for our phone and it has only 200 kb.

Review 20 by takumibunta: First option, I suggest you to use the ONE POWER GUARD app… The latest version is stable and there is a battery calibration function in the options.
Second option, download ‘battery calibration’ in the Google Play. Just for simple battery calibration only…
I STILL RECOMMEND ONE POWER GUARD. IT CAN OPTIMIZE YOUR KERNEL, ROM, WI-FI, 3G AND I/O SCHEDULER SO THAT TO MAINTAIN BATTERY LIFE. IT’S A NICE TRY.
Here is the step (The developer recommend us to follow these steps but not necessary)
THE FIRST AND SECOND STEP IS THE BATTERY CALIBRATION PROCESS
1. CHARGE your phone to 100%
2. Click on battery calibration button first (battery calibration app or ONE POWER GUARD app), then only plug off your charger.
