I used this last night, on a friend's S4.
I also used it last week to Mod my Nexus 4
On a phone of that age, I'd be shocked if it was the ROM causing it, and not just the age of the battery.
My S2 lasted about half a day until I put Cyanogen on - I get just about a day now.
My wife and I both have an Xperia U, I updated mine to ICS, rooted it, took off the unneeded apps. She left hers at stock Gingerbread.
I barely get a day out of it now, hers goes on forever. :mad:
Though I did read somewhere that Sony's ICS update was less then ideally implemented.
'Bootloader unlock allowed: Yes' cannot be achieved whilst the phone is locked to a specific carrier, according to information I found when I first got the phone. Which is why I need the unlock code from EE (I could buy it from one of those dodgy-looking sites online, but as implied by 'dodgy-looking', I don't trust them)Quote:
In your device, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
I honestly have no idea. To stop you getting a new phone from them with a cheap contract and then a phone-less contract with someone else for the sim (therefore they don't get any cost for any usage over the limit)? But given you can't get new[er/est] phones with cheap contracts, and you're tied in and have to pay off the charges for the life of the contract even if you cancel early, I don't see the point. Either way, they're getting their money. Surely going over your limit isn't that expensive.
