I purchased Nokia E7 two days back and found the battery discharged even it is not in use. I charged completely but after some times its signal showing battery low. Can any body help me to know the reason and how it will keep battery charged.

Thanks & Best regards,

How long does it take before the battery is discharged?

Usually it takes a few charging cycles to get optimal battery performance. You should also concider turning screen brightness down a bit. Do you have bad 3g coverage? Have you set up the phone to sync emails etc? Do you have whatsapp?

The battery life on my E7 is pretty poor, especially when running lots of applications or 'live' widgets, try what Fender suggests, but depending on what you're comparing it with, a Smatphone with a 4" screen is not going to last much more than a day even with light use, there are several threads on battery optimization on the forum. I just charge mine fully over night every night and top up at work as necessarry !

Good Luck

If you charged the phone overnight and it discharged in an hour, it is faulty and requires replacement !

Send it back !!

[Fender77]

Yep, as carman has already pointed out: demand a replacement. Good luck.

I had the same experience and realied that it was Whatsapp that was draining the battery.

Apparently there are sill some background processes even after you kill whatsapp that is running before.

Kind of had it resolved when I switched to using GSM instead of 3G connection.

Was hence able to run whatsapp without draining the battery.

These days my battery can last for more than a day.

Hope this helps.

DId you experience battery draining from full to totally discharged in 1-2 hours with whatsapp on 3g? I know whatsapp is a battery eater, as I had it and uninstalled it for those reasons on my E7, but it never drained a fully charged battery within 1 hour. That's wierd, but I guess it's possible, though it has to get really stucked accessing web constantly and at the same time trigger cpu to run as fast as possible...

Mine lasted possibly 4 hours less with whatsapp, but it still lastet about 8 hours.

[nickygoh]

Wow, 1-2hrs discharge is a guzzler.

Mine was about 4hours, before whatsapp did the software update.

I don't go on 3G anymore after the update so I'm not too sure if it lasts a bit longer.

In fact my battery lasts better after I switched to GSM full-time so that might be a factor bundled with whatsapp.

Hi

I got E7 10 days bafore. Im on 3g, 2 emails account that sinc every 30 min. For that im using wireless, not gprs (not configured, only wireless for internet). It takes 2-3 days to discharged, depending on that if Im using other apps or not.

This weekend used sports-tracker during my bike ride. It takes less than 2 day to discharg.

My battery looks ok?

Compare with ur it is. What others can say?

Baterry should not be fully discharget when you purchased it. Maybe to compare call duration in your log with life timer u got with code *#92702689#. If you did not reset ur log.

Your battery seems just fine fani_sa! - Nothing to worry about!

It's right as you say, batteries nowadays usually comes with about 40-50% charge from factory as it will be the best condition it to be stored over time.

[carman58]

@fani_sa, do you want to swop handsets ? Mane won't last a day whatever I do, unless I just don't use it !!!! 

[fani_sa]

with pleasure! but how? it can not be removed.
