Iphone 4s doesn't lag, and very smooth when navigating the UI, it may suffer very little lag, maybe not noticeable if you won't put much attention to it and still looks smooth afterall, especially when the assistive touch is turned on while transperancy is also on. But most of the time, it runs smoothly with assistive touch turned off, and might not experience any lag.
i usually don't use assistive touch coz it causes lag in some apps like messaging and appstore, and sometimes on animations and transitions.
battery backup is depends on your usage, if you're a heavy gamer, then battery will just last for 4-5 hours with 3g activated.
for normal use, it will last more than one day.
i love this phone for gaming though some latest games aren't run smoothly, like real racing (which is heavy in terms of graphics), but old games like dead trigger, and others run without lag.
internet is good, but sometimes 3g usually drop and needs to open safari to reconnect the phone to the internet to use appstore or any 3rd party apps that needs internet. (this happens very rarely) so nothing to worry about.
overall this is a great phone and it still last for more than a year from now and still remain a great phone.
if you plan to upgrade, don't go for iphone 5, jumped to either iphone 5s or 6 coz it's the start of new iphone generation with faster chipset (64 bit), coz iphone 5 will suffer what iphone 4 had in terms of os update and hardware gap within it's successors.

Ur absolutely right ..m also facing same problem Main drawback of this device is battery .. It drains too quickly .. I dont know why apple giving small battery life to their smartphones .. Iphone 5s has also 1560 mAh battery .. As they are selling smartphones at very high price .. They should give bigger batteries to their phones .. My 4s battery drains out within 4 hours .. On 2G .. It sucks .. I have to charge more than 3 times a day ..m very dispointed Decided to go back towards android platform
The major drawback of 4S is its tiny battery. I dont know why Apple can't put some decent battery in their phones when we pay them such a high price. Atleast 2000mAh battery can be given.The battery drains out within 4hours if you use 3G. And for 2G its 6 Hours maximum.Had to charge several times in a day. Not at all gud for people who are frequent traveller.
