I bought this battery on the strength of the other reviews. I was wary at first as it is less than half price of an official HTC battery, but I am very pleased with the purchase.
My Sensation would be dead after 8 hours (from 100% at 8.30am to 10% at 4.30pm), this was with a handful of phone calls, texting throughout the day, Facebook and news updates and the occasional blast on a game. I knew the battery life was poor prior to buying the phone, but didn't realise how bad it actually was. HTC seem to think it is OK to fob their customers off by telling us we can achieve a greater battery time by switching notifications and settings off, and limiting the time we use the phone. I am sorry, but this just does not cut it. HTC should ensure battery life is optimal, and as standard, it clearly isn't as this battery lasts a lot longer!
With the Anker battery, the phone left on idle stays on 100% for over 8 hours and I assume would last a couple of days if left on stand-by. With my regular use throughout the day I am now going home from work with nearly 50% left, rather than 10-5% on power save! It also seems to run cooler (my pocket and battery indicator app confirm this).
I ensured to charge the battery whilst the phone was switched off. This took just over 2 hours. For the first few days I made sure to use the phone even more than usual and the battery still held up all day! I can leave everything on (gps, wifi, etc).
I highly recommend this battery. So far it has proved to be a worthy investment; however, it will be interesting to see how long it lasts before having to buy a new one. I am surprised (and almost angry) that HTC chose not to use a higher powered battery as standard? It would be interesting to hear their reasoning as to why, as it is insulting to think they have the option of a higher mAh battery available.
One issue I have is with the conflicting warranty - the leaflet says 1 year, the packaging says 6 months? Either way it is nice to know you are covered by a manufacturer's warranty, regardless of how long it lasts.
5 stars for now and will update in 6 months of use.
