That was a spicy reply, MistahBungle
- No system update was installed in the last month
- No application has been removed
- System hasn't been rebooted for a month or so
- Never got more than 2-3 days out of battery in idle
- Battery is 2 years old and is physically not damaged or swelled
- GPS isn't working (not even receiving or predicting a satellite on a clear day)
- System is rooted for a year or so
- Battery lasts 4 days now (instead of <2days a month ago)
- Connected to 3G network (no data connection)
I would try to reboot my phone, but I am afraid that it will all be over...
So, to stay with firm facts - how much battery life do you get with alternative ROMs in real life? Is 4 days (5-6 days with new battery) something usual?
That concept defies logic given GPS only uses battery when you're actually using it.
Can you then explain me the difference between Cold and Warm GPS start? As far as I know, phone tries to keep as accurate GPS time as possible and a bunch of ephemerisis data in order to decode GPS data faster, next time you enable GPS. This defies logic that GPS is completely OFF when it is 'disabled' by GPS button in Android system.
I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ?
No, I don't expect it to. I am looking for information whether anyone experienced anything similar.
Did it ever occur to you that given the battery is two years old it's quite probably on its last legs & is very likely chemically unstable (this is why 'old' batteries swell up & sometimes even burst). This instability might be causing the extra battery life as the battery approaches the point where it's no longer useful.
In Lithium-powered batteries, I haven't come across the fact that battery capacity is increased with battery ageing and sweling up... On the contrary, internal resistance goes haywire and capacity drops, contributing to even more heat being spent internally by the battery and speeding up the process of degradation...
I may have not been cooking my own ROMs and writing drivers for phones, but I have quite extensive background in embedded systems and electronics. Battery life can not increase just by itself - there must be a reason... My lifestyle hasn't changed, my environment also didn't change, other phones at home didn't experience such battery life extensions... The only thing that I noticed is that the GPS is not working. I opened this topic in order to discuss whether that's the true cause or not.
So, based on '3 yrs worth of different people's experiences on here', what could be the cause for such prolonged battery life? How can I debug it by myself without rebooting the phone?
