Will only hold charge for about 6 hours. I get 7 hours if I take it of the charger and don't turn it on until close to end of work day. Sent back to Blackberry. Said they repaired it and replaced battery. Still does the same thing. NO serious Apps installed....no pictures...factory setting at this time.
I'm pretty sure that's normal with most Z10s, as I've experienced reading around CrackBerry. I myself, have a Z10 that lasts 5-6 hours, and reading around the forum, it seems to have an average of 6-7 hours.
The Z10's biggest problem is none other than its battery life.
Go get yourself a powerbank.
There's also the option of buying a bigger battery, but it may require you to also get a bigger battery cover, making a bigger phone in general.
