Whatsapp updated just this morning and my battery drained like hell, even after I closed data connection. Restarted the phone, before restart the battery was 36% and after turning it on the battery 25%. Anyone experiencing this?

maybe you need to turn off photo from auto uploading to skydrive... or if your phone is new, you need to use it for at least 2 weeks to get the battery's optimum performance.. hehe...

I deleted whatsapp, drain battery gila gila punya.. Idle oso makan bateri...
will reinstall if whatsapp team design it but not using music api to make sure wifi is on..
only wp7 needs this, wp8 no need according to the comments i read

no i mean before this the battery was normal, lasting to 6-8 hours with data on. Then I updated whatsapp this morning and somehow the battery drained so fast. And also like i said before turning off phone the battery was 36%, then turned it on again got 25% only. How can battery drain when the phone is off?

Yesterday with whatsapp on, i on navigation, plugged in car 2.1amp charger, 1.5hrs trip, took 30% battery... Fuuhhh..., imagine how of i did not plug in charger at all? Sure batt depleted b4 i reach destination..

today after uninstalled whatsapp, use about 20 minutes of navigation, battery still at around 90% without plugged in car charger.

my chargwr is neq, and definitely working not rosak..

The battery drain happen not when the phone is off but when it boots. The booting process takes a lot of power.

Yeah you got a point there. But I think 11% is too much. Or maybe the battery status is not accurate ie slow update

try uninstall and install back whatsapp...
i have updated mine this morning too to 2.9.4...so far the battery drain seems normal...

I update my whatsapp but my battery still just normal

My phone finally faces the self reset problem. Now is the 3rd time

Yup. Maybe the indicator not so accurate.


Some users say delete the apps designed for WP7 will solve this problem. Only install those designed for WP8.

I wonder what wp7 apps are causing those problems... mind sharing it to us?

Anyway Portico OS version is 8.0.10211.204 right?

Are there any way to know if which app is a WP7 app?

They said check the app last updated date. If it is before Nov / Dec 2012, it means it is not optimized for WP8 yet.

Yup, that's what I heard. I'm not sure if there is a proper way to find out whether it is optimized for WP8
