But yes, there are cases reported when battery level get stuck on 100% when charging on some USB ports. I think its more to do with the calibration of battery. Being said that, I charge my Neo through wall charger, laptop and my cheap desktop and never had any noticeable difference in discharge pattern. I had this 100% battery stuck issue, but a battery wipe from CWM recovery did the job.  |
Thats right, even though it may show 100% you may get less juice out of the battery if you have charged it thru a USB port. I'm guessing that its due to the low quality PSUs used. PSUs can be pretty dangerous things. Due to severe cost cutting, many do not have adequate filtering and protection from issues like over current, short circuit, etc., and poor quality output with high ripple & noise. High quality PSUs are usually used by gamers or enthusiasts as they cost a lot more. I'm pretty sure the average household PC and office PC would be using low cost PSUs. In fact, other than gamers and enthusiasts, nobody would pay much attention the quality of the PSU. This obviously has an effect on the life various components in the rig. I'm guessing that branded laptops may be using better quality stuff, but who knows. I don't have the equipment to verify. However, the possible effect is very much there - that batteries charged off USB ports don't seem to hold nearly as much juice. This is not just my experience, but has been observed by many. So there is plenty evidence to suggest that charging off a USB port may not be the best thing you may be doing for your expensive phone. At best, battery may hold less charge; and at worst, you may be reducing the life of your phone. Quote:

Unless you want a slightly heavier phone with a bigger battery your problem of lesser battery life will never be resolved.
May be advancement in technology will lead to smaller batteries giving better life and i still believe people will opt for devices which are not so ok in battery and go down on size.
For example if there is atechnology that gives 2 days battery life for the S2(lets say) i am pretty sure people will be ok to get a slimmer S2 with a 1 day battery life using the same technology which will push more energy in a smaller size battery.
I simply dont whine for charging my phone. Its just part and parcel of having a device as big as a tablet.
Gone are the days of using Nokia where the phone was heavy, clumsy and had great battery life because the battery itself was heavy and big. |
What you say has a point. We all would like slimmer, lighter devices, however, one has to find a balance between the two. For eg. most manufacturers still seem to think that battery back up is the last priority. For eg. take phones like the Galaxy Ace. 3.5" screen, Android and just a 1350 mAh battery?! I know a few who need to charge it twice a day with moderate use! Besides, using battery in this way will severely shorten its life and you would need to replace it pretty soon. Why can't they at least supply a battery of 1500 - 1700? I'm pretty damn almost all users won't mind the very small increase in weight and cost. But no, for whatever reason, they do not consider it important, which is a shame. The Optimus One for eg. has a 1500 mAh battery and can plod along for some 2 days or a bit more, but only after disabling a lot of things and effectively turning it into a dumb phone.
Its well known that battery tech has not kept pace with advancements in other fields. Some major developments are required to take smart phones to the next level, if they are to remain "smart". Lithium Ion is not going to take us there. |
