Dankorw Posted April 19, 2013 Share Posted April 19, 2013 Hi guys, I'm wondering if it's a good idea to replace my old battery on my iPhone 3G, since it always last a couple of hours while surfing the web or trying to use google maps or using 3G/WiFi related software. My iPhone is jailbroken with redsn0w_win_0.9.6b4 and got the 4.2.1 firmware. I could use even some tips in managing its ram with anything since sometimes it could be REALLY laggy. Thanks!

Harkey013 Posted May 8, 2013 Share Posted May 8, 2013 Hi it's a great idea to change your battery and at the same time you can fit a higher capacity one. My old 3S was hard on the battery after a OS update and the advice I found was to disconnect the battery and reattach it to recalibrate the phone, so I thought I would update the battery at the same time. It can be done easily yourself but my eyesight let me down, picture trying to reconnect the small plugs and holding a magnifying glass at the same time. Any way my niece has had the phone for the last year and battery life is still great. Cheers, Ken. Link to comment Share on other sites More sharing options...
