i bought a blackberry Z10 last year may, between then and now i have changed battery up to 3times already, plz anyone in the house who can help out on how to solve this problem?

Its the phone. Older models of Z10 have problem with calibrating battery percentage and it was fixed in later models. Ve forgotten the defective model number. So the battery that came with the phone originally is good just that when your phone says 80% its actually just 2% hence the phone will shut down. Buying a new battery doesn't fix this.
Is either this or you have been buying fake batteries.
Work around is to make sure your battery is empty (you can do this by switching on the phone continously until it no longer comes on) then remove battery from phone and let is stay for about 6 hours or more to ensure no charge left. Then put it back and charge phone to full. Remember this is a temporary fix cause the problem will result again after some days or weeks.

Remember after putting the battery back after waiting for 6hours ( it can be less) the way to know is after waiting for like one hour and you put the battery back it should start from 0% if it starts from more than 10% (usually you'll see 80%) then you have to discharge they remove the battery again and wait for longer

I use a Z10 since the first quarter of last year and I haven't changed the battery that came with it and I don't regret it. must everyone follow the overcrowded Android population? To me droid looks like stuff for kids who always need something to play with.

yeah i tried it yesterday but i bought another battery anyway cha, tenz for all ur contribution, and there told me not to use desktop to charge again.
