how much

May I know the unit you get from seven mobile is SIS unit or Brightstar unit? Want to check with you whether the seller can be trusted for real. Since they are selling so cheap, almost AP price.

10 mins gaming = 30% drain? did u switch on wifi hotspot at the same time? GPS?    perhaps the battery is not properly calibrated. drain it to zero n recharge till full n see? but not advisable to drain ur battery to zero all the time, not good for battery lifespan, just for re-calibration purposes. if u still have this problem it might have been a defective battery... what games do u play?

ps. oh okay fast n furious. no wonder battery drains so fast n furious 

wait for the other forumer's advice. as my advise might not be the best advise  how long have u been using ur HTC One? perhaps get an app to monitor ur battery consumption?

Yes..same goes to me..
just use it few hours n its damn hot la weh..
i just bought this phone yesterday n just play around with sosial media n do some downloads it n getting hot..some more it drain battery very fast..so any advice taiko2..

help2..

battery drain issue..
first... throw away mind set  of comparing to note 2....the battery on HTO is smaller than note 2 thus lifetime shorter
second, the phone is actually a heat sink...so the aluminium will disperse the heat through the aluminium, that is why u feel hot fast.... but actually it keep the internal good, i used to have sgs2, it is very hot when I use long and it was plastic but i dont mind, just put a case and it doesn't bother u much
third..turn on ur power safe mode, it will increase the battery life
fourth... close gps, bluetooth and wifi when no use, it eat battery damn fast
five.. LTE eat battery, so when you not require surf fast, or not your area no LTE, change the network setting to GSM / WCDMA auto or even better just WCDMA only
six...how many social media u have? the more it sync the more battery it eats
seven...how many hours you you on social media? if you continue for 4 hour straight, of course it drain fast, you need to post some more information, are you on youtube or streaming
eight.. have many cycle battery you gone?

My battery range from 6 hours to 13 hours average depending how long n how I use...i have damn a lot social media, whatapps, twitter, fb,badoo, tagged, twoo, tapatalk, viber, wechat, google+, kakaotalk, instagram, blinkfeed, 3-4 email sync..but i still manage 6 hours...way way better than my sgs2..
if you compare with iphone or note 2 or worst bb...you can't compare

i'm going to bulk order from amazon....
anyone interested to join order....?
