Hi all,
does a phone battery die suddenly with no warning or is it a more
gradual process with the battery holding less and less charge after
each recharge?
Since last 2-3 days, my phone battery is running flat after 3-4 hrs.
Problem is I also did a os upgrade (Android) a few days ago! ... Why I
think its the battery and not the os upgrade, its because it seems to be
getting worse - (just now its loss about 15% in about 20 mins and
its just idle)
Thanks,
Daniel.

As David observed the battery MAY be getting old;
but why not fully charge it and remove it from the phone;
then reinsert it in the phone again after 3-4 hours ,
and recheck ?

When you say 'idle';
that is as indicated by :
Settings>Developer options>show CPU usage ?

Chances are that there is a process that is chewing up CPU and therefore
causing your battery to be more engaged.
Also, when doing upgrades, it is normally a recommendation that you
don't do so unless the battery is fully charged and the phone is
connected to power (this is for a number of reasons).
If the battery wasn't fully charged when the upgrade was done, then
there may be an issue requiring a re calibration of the battery; perhaps
doing that will help.

Phone was connected to
charger during upgrade, but I dont remember if it
was fully charge, but I'd say +75%, this phone is rarely below the 75% mark.

I have done that 2 or 3 times already
(drain to 0% and recharge to 100%).
I will backup important data and reset it to factory default asap.
Daniel.

I installed a few upgrades to android after I mysteriously got enough space
back on my phone to install them..
And noticed the phone getting hotter and power usage higher than normal too.
Turns out an old app I didn't need any more (the optus one to show you
your data usage)
had kicked back into gear, but couldn't access an optus server, because
I'd changed
to boost.
Once I uninstalled the optus app, the power drain disappeared.

yup. 99% of the time 'power drain' is a bad app.
could be hogging and burning cpu, or just looping and crashing.
things change between android versions (eg. APIs, SMS db schema) and
sometimes old apps can't deal with it.
first port of call in android 6 (and 4.4, which is what I have handy) is
settings -> battery
and look at the top apps. probably it's the same in any aosp variant.
the same display is in sony android 5.1 as
settings -> power management -> battery usage
and whichever android flavour you have, it'll be there somewhere. it's
an aosp thing.
if that display fails to finger anything, then something looping and
crashing will be super-obvious in logcat, so attach to a laptop with
adb and you might be able to see it, although some of this logcat
functionality went away with android 5 permissions.
or root it, and then give permissions to alogcat app, or install
cyanogenmod instead (and then you can click a few menus to enable root),
or... many thing. you could even try one of the 'battery
optimisation/drain' apps which are probably in the top 10 of malicious
and/or battery drain apps out there :)
or
echo rootmydevice > /proc/sunxi_debug/sunxi_debug
hehehe
the summary is that there are many ways to see what's going pear
shaped, but sadly none of them are particularly obvious or easy.
I guess this is fundamentally due to the "always killable/restartable
app" model and event driven nature of android, combined with the
strict permissions and isolation design. android is really entirely
unlike linux apart from the kernel and busybox.
cheers,
robin
