Hi guys, i am new to apple. currently have the I phone 5 and yeah at first i did face huge battery problems but thats is basically because i didnt know much about this phone. Big gadget fan here. Anyways about the battery problem, i think i have the solution here. You all have to remember that this is a very powerful phone and with the size that it comes in, i dont think a small battery will be able to provide the necessary juice, But there is a solution. I get upto 14 hrs of battery life and on an average up to 12 hrs. OK this is what you need to do.
only keep the notications you see often, on like whatsapp, viber,messenger. and what not. switch of Siri and only switch it on when you have to use it for something. mails and other things all manual. now this is this the main part that drains out your battery, try as far as possible not to switch off the phone from the power button which is on the top. for this put on the automatic swicth off and set it for 1 minute. that is it!! trust me it will work. after you set this, let the battery come to red and charge it for like 4-5 hrs. by the next day everything should be fine.
Remember, DO NOT USE THE POWER BUTTON TO SWITCH OFF AFTER USE, LET IT SWITCH OFF ON ITS ON. also use, in the accessability the gesture app to usw your phone.
after trying this out, get back to me and tell me if this works for you all.
