The maxcapacity is low for many because u have too many cydia tweaks which are shortening ur battery life. I uninstalled a bunch and left only the necessary few and my maxcapacity has been at a constant 1422. I can confirm this as i reinstalled those tweaks again and my maxcapacity dropped to 1360...
How accurate is 'Battery Info Lite'?
Figured I'd give it a try. I have an iPhone 4 which was pre-ordered and sent to me the day before release day. I'd say things are about normal considering it's been two years.
I charged the phone overnight, received two text messages and sent one. Then I noticed this thread and here's what I have:
I doubt it's accuracy. The other day I drained the battery unintentionally to zero and fully recharged their. The charge cycle remained the same value.
The number you see in program for things like Max Capacity, are an approximation. It's usually fairly accurate, in most the details; but there can be reasons it misses a charge cycle. Letting it die is likely one.
Also as for Cydia apps having an effect on Max Capacity, I've found that unlikely (unless it's poorly coded of the hooks conflict with another app). Seems its more about being anal about charging and taking care of your phone.
I've learned never let it over charge (But let it sit at 100 for at least a few minutes before unplugging), sometimes it helps to drain it to 90 or so then charge to full again randomly once or twice a day.
Again, don't leaving it charging over night or over a long period of time >__< (My sister seems to not get this). With this pattern my batteries back in the 1400's; 1413 at the moment. >__>b
I believe the program might actually count the drain cycle rather than recharge cycle. That means using the battery from 100% to 0% counts as one cycle, rather than recharging from 0% to 100%. That is what i observed with iStat Pro on MBP.
