Sony Ericsson K700i

Hmm, now let's see. A new battery costs £20-45, an upgrade after one year from £0 (provided you are happy with an end of line handset).

Upgrading for a more modern handset or smartphone is another story .

 

Should you decide to buy a new handset then, a good battery is still a worthy consideration Hope though you'd get a better, longer lasting battery that'd be compatible with whatever handset of your choice

good luck



regards

 

There were problems with the K700i battery life before the firmware got updated. Make sure you have the new 2nd version. Plus some ppl have used a Nokia 1100mAh battery with good results, see http://mobile-review.com/forum2/showthread.php?t=16260

 

Thanks Mike, do you know how to determine whether the phone has the second version of the firmware? and if it's possible to upgrade it?

I'll check out the SonyEricsson site.
