    Never said it was. I said that what I do. Wasn't telling anyone else to do it. It works for me - redundant though it may seem.

    I'm just trying to understand the logic behind it.

    Oh, that was the misunderstanding. You assumed there was some logic involved. No, it's just what I do,

    I'm impressed by the results. I updated to lollipop this morning and it was a bit laggy / hesitant after. Didn't want to fool with a full factory wipe as I'm on a trip visiting family with my son. But did the cache wipe and WOW. Everything is now super responsive, lag free. Have too see about battery, traditionally I've made it through one day and charge while sleeping.

    Thanks for this tip. I'll do it to my wife's S4 and mother-in-law S3 when I get home. Hopefully help their battery performance.

    Man, even my SwiftKey is super fast now.

    Happy!

    So, I attempted this today. While booting into recovery mode and my up volume button was still pressed, I got the android robot on my screen with the message "updating system" or something like that. After about 10-15 seconds, it says "error" then the menu pops-up. I clear cache and reboot. Try again to see if that happens again and it in fact did however, both times I get the message that says cache delete complete.

    Normal?

    Right on. I'm not worried about it or being paranoid just thought it was odd seeing system updating followed by error.

    yes, I get the same notification. At first I thought it was really trying to re-install the OS update, but it went pretty quickly to "cannot find" something, and then on to the cache cleaning, but it took like a second to do the cache clean.. shouldn't it take longer?

    anyway, still operating at well below regular battery life, about 50% of previous battery life expectations. not sure what to do next other than a full reset and re-install everything. which is such a pia.

    I have so much on my phone since I don't even touch my laptop anymore. If it got to the point where I would have to either factory reset my device or suffer through sub-par battery performance, I'd suffer through the sub-par battery performance. There is no way I'm factory resetting my device unless it is absolutely necessary.

    Here is a suggestion uninstall the largest programs then do a program cache cleaning(ccleaner, 360, there are many) then reinstall them. Next load a app like Greenify and setup to hibernate programs which sit in the background which really drains the battery then execute them when needed then again hibernate.

    I was having trouble with this not 3 days ago. I searched for a good hour or two on Google, until I found this same thread, only for the S5. The cache cleaning solution was also mentioned there, and bam. The battery life is back to usual.

    For me it was the Android System that was using it all with "CPU Total" and "Stay awake".

    thanks for this.... so much knowledge on this site.... my battery has never been better. another tip was using power saving mode (not ultra) and boom....36 hours of battery in normal use.

    Ok so I deleted the cache but my battery is still pretty bad, it might've gotten worse like 2 minutes per percent. however, the performance noticeably improved

    Need more info - are you running anything at the time? Have you used any OS monitor app to see what might be running and using CPU? Is the screen on and at what brightness?

  19. Savan01's Avatar
    I typically have power saving on with my performance limited and have low brightness, the apps that usually run in the back are as follow

    android system at 29%
    android os at 11%
    screen at 11%
    cell standby at 7%
    battery widget at 6%
    music 6%
    twitter 5%
    device idle 4%
    media server 4%

    Personally, yes. I was seeing my battery life degrading, not terrible, but noticeable. I deleted a couple of suspect apps and cleared the cache. I noticed the difference right away.

    If you don't mind me asking, in 15 minutes, how can you tell if it's better or worse? I highly doubt you can tell if your battery life has changed in such little time. There are some days where (any of) my phone drop faster the first 10 percent, or the last 30 percent... I'd have to do a full charge discharge to see if it's any better or worse.

    If battery issue, delete cache, fixed my battery issue-capture.jpg

    To wipe the cache partition, follow these steps:
    1. Turn the device off.
    2. Press and hold the following three buttons at the same time:
    • Volume Up key
    • Home key
    • Power key.
    3. When the phone vibrates, release the Power and Home key but continue to press and hold the Volume Up key.
    4. Continue holding the Volume Up key until the Android System Recovery menu displays and then release. This step may take several seconds.
    5. Press the Volume Down key to highlight 'wipe cache partition.'
    6. Press the Power key to select.
    7. When the wipe cache partition is complete, 'Reboot system now' is highlighted.
    8. Press the Power key to restart the device.

    It really worked. I was going from 100% to 88% battery in less than five or ten minutes. After doing this it went back to normal. It's like my phone is brand new again. Thanks.
