How to test HTC One X battery life?

    Sorry Jayce But I Think U Make Mistake By Investing Money In This Handset..You Should Wait For Galaxy S3…

    • ako

      this hand set is nowhere near expectations. i hope the same doesnot happen to s3.

    • onex

      • htc

    In one hour a 12 % decrease is too much and considering it is in air plane mode. How can you say the battery life is ok. I mean i thought my s2 had a poor battery when in one hour with phone and sms sevice on it dropped by 6 – 8%.

    • 4.7″ display with max brightness eats lot of battery.

      This is the HTC battery test, not to be confused with actual usage drain.

  • fml

    ooooooooo i was actually considering this. looks like i better wait

    • Torbjörn Hagel

      This is the HTC battery test, this is what they use if you send it back for repair or a DOA claim, not to be confused with actual usage drain. Everything above 30% is acceptable as stated in the test.

    hello jayce,

    so, overall, do u recommend htc one x ?

    • Not a perfect phone. But it does have some advantages that I like. Wait for Samsung Galaxy S III, then decide…

  • Jed

    hello jayce,

    i tested my htc one x and my battery level reached the limit of 70% after one hour of testing. My battery monitor also indicates overheat after the test. Should i seek manufacturer to replace my device? I only had the htc one x for 1 week.

    • Yes Jed, do consult HTC Support.

    Hi, I’ve done this battery test 2 times, the first time, I was left with 72% and the second time I was left with 75%. I believe it is too low because in your test you have 88% left. I was down to 88% already after 30 mins. Do I have to seek replacement for my device?

    • Hi Bernard, you can try. 😉

  • Paramvir Karir

    I got 93%

  • haris

    I got 88%
