Perfect deep sleep, yet still battery drain

[AndroidGx]

I wonder why my battery is like this:



There is really no reason, the phone was awake only for 7 seconds. Is it defective battery? Mine is 1 year old. I don't have other battery to test this. I also charged the battery to 100%, then powered the phone off and pulled out the battery for 3 hours. The percentage was 94%. Any ideas?

You might want to try uninstalling that 'Deep Sleep' app and just rely on the Android battery saving features.

Because the app is lying and is snake-oil possibly.

No, even when this app (BetterBatteyStats) is disabled, my battery is still worse. Sometimes -10% for 1 hour, other times -5%. It is pure random. I forgot to mention that I am using unofficial custom ROM build. The battery is not dropping that much on the stock ROM, but I have other problem with it - after battery percentage is down to 50% and if after normal usage I reboot the device, the battery will literally drop to 5% or 10% after booting.
