hello....
anyone face this problems before which is I'm fully charging my phone (shows 100% (plug in) but when i unplug charger, there straight shows only 96 or 98% only.... anyone face it before?

How long have you used the phone? How often do you charge your phone?

November 2013. Normally is one time per day.... sometimes 2 times but i think this just happen 5 times only

not sure if your battery is wearing out. just my 2 cents though.

do you facing this problem?

Guys, need a fast reply here. my mum's K900 battery have this kind of problem where the battery percentage stays at 100% then suddenly reduce a lot (sort of calibration problem). Most probably due to using my dad's Lenovo Yoga.

Advise.

try completely drain the battery and charge it to 100% again without turning on the phone, see if it works.

My phone keep stuck on Lenovo welcome screen. What should I do now?

you are experiencing bootloop. try enter droidboot, clear cache and see if it helps.
if it doesnt works, its time to flash your phone.

I has try all the method but no use. If I want to flash, how should I go about it? Can you advise me?

what about factory reset?
if you want to flash, here.
