Hello.got xperia m before 4-5 days.its with cm11 and i got an issue with battery.when i charge my phone close i can see that it is 100% charged.but when i open it it drops to 95% fast. Same thing happens if i charge it open. When i replug the charger it goes to 99% normaly but after it takes much time to go 100%. Is this normal?i also try calibrating battery removing battery.bin and also tried removing battery for 10min.no luck at anything
It looks like it has some wear. Because you're probably out of warranty by flashing another ROM, may be it's a good idea go searching for another battery. If I'm not mistaken, there are some 1900 mAh batteries arround compatible with Xperia M (the default one being 1750 mAh).
But you can try to turn airplane mode on, then go to Settings > Performance > CPU and setting maximum CPU speed to 486000, as well as the CPU governor to powersave, then checking the option to restore these options every boot. Level brightness down to the minimum.
Now, let it charge to 100%, disconnecting the charger, after. See if it drops. If it still dropping, it's battery wear. Of course, the time it lasts depends on how much time you spent with screen on and what tasks are you performing, i.e.: if you're playing Fruit Ninja right after disconnecting the charger, with medium brightness, it's not imposible to drain 7% right at the first three to five minutes.
Well, may you post a screenshot of battery usage graph?
Ok.battery seems to work fine.phone charges to 100% and it holds 5h and 45min of gaming with low brightness.i charged it full,removed charger and i go to sleep.when i woke up (after 6h50min) phone was still 100%.i guess that the phone wasnt charging full cause of the way calibration i did by removing battery.bin....
