How long is an iPhone battery designed to last?

I checked my cycle count of the battery using ibackupbot and it told me it has 1,020 charge cycles. I only did this because it dies pretty fast (about 3 hours) and I have to recharge it 3-4 times a day. Also, when I restart the phone sometimes the percentage will jump up about 20 percent higher than before the restart and then slowly climb back down.

Buy Samsung Galaxy, is better in terms of battery life

All rechargeable batteries only last about a year before noticeable changes in performance occur. After 2 years, they are pretty much done for.

This assumes one charge daily.

That should help, but either way it sounds like you need to get your battery replaced.
