GUIDE: Android Battery Conditioning
Want 20% better battery life on your Android phone? Here’s what, why and how. But let me give you this caveat – a 20% increase on a battery that is giving you 3 hours isn’t much – probably not worth it. I mean, if you currently get 5 hours, you’ll only get maybe 1-2 more hours max. However, if you have an extended battery, 20% might be worth it.
Me, I doubled the life of my Thunderbolt battery (1400mA) by replacing the battery with the exact same size replacement battery for the HTC Rezound (1620mA) – from 3 to 7 hours of battery life, no rooting or conditioning required. But of course, I want MORE! So here’s the directions.
WHAT: Battery calibration is getting your phone to recognize the full capacity of the battery.
WHY: Lets say your battery is @ 80% actual capacity when your phone was set up at the factory, or when you flashed your new ROM. When it hits that 80%, it stops charging! You need to reset that stop point at the ACTUAL 100%.
HOW: To correct it you “bump” charge your phone back to 100% actual battery percentage and wipe your battery stats. Now you have set what the phone thinks is 100% to what IS actually 100%.
Battery Conditioning
B. Bump Charge your phone to get it to ACTUAL charged capacity
- Charge your phone until fully charged while powered on.(IE. Green LED light.)
- Unplug your phone from power, wait 5 seconds and plug it back it. Repeat this until your phone stays at/returns to 100% within a few seconds, then Turn of your phone.
- Charge your phone until fully charged while powered off. (IE. Again, green LED light.)
- Again, unplug your phone from power, wait 5 seconds and plug it back it. Repeat this until your phone stays at/returns to 100% within a few seconds.
- Boot into recovery and wipe battery stats.
- Reboot phone normally.
