do iphones charge faster on low battery mode

Their internal logic does not cope for a very flat battery. I have found numerous times with so called 'smart' battery chargers as needed for Li-Ion but also NiMh or even lead acid leisure batteries that they refuse to charge a really discharged battery. I've done this a few times now on various different models and it always works. After about 10-20 mins, enough charge should get back into the battery to fire up the phone and it'll come back to life. Immediately reconnect the battery into the phone and put it on charge. Heat it for a good 5-10 mins so that the hear soaks right through the battery and it feels hot to the touch, this will raise the internal voltage enough to reconnect the protection circuit. You may get away with leaving the phone overnight in a very warm (hot) place, such as on top of a hot water tank, however a more efficient way is to remove the battery and heat it up until it's quite hot with a hairdryer on its hottest setting. You only need to get the voltage in the battery to raise a percent or two to reconnect the protection circuit so that it will charge again and you can do that by warming up the battery. Unfortunately, once this has triggered, you can no longer put charge back into the battery because the battery is disconnected internally, so no matter how long you leave the phone on charge, it remains disconnected and flat. Lithium batteries have protection against over-discharging, they do this by breaking the circuit if the voltage drops too low to prevent further drain. Ok, this is too late to help, but I thought I'd answer anyway in case someone else finds this post whilst searching for the problem. I've had the phone for about seven months, but it was a refurbished unit from Apple. Is there any way to help pinpoint the cause other than guess and check? If not where should I start? Has anyone seen something similar to this? I figure at this point I can't make it any worse. It's out of warranty, so I'd like to try fixing it myself. It seems like it might be the charge circuitry or the dock connector. My first thought was the battery, but after reading some posts here, I'm not so sure anymore. I can't get back to it unless I repeat the process from the beginning. If I hold them down for about a minute, it will actually keep flickering until finally it shows the dead battery screen, but that will go away in a few seconds or as soon as I unplug it from the wall. I left it on the wall charger for several hours, and I still got nothing.Īt this point I tried rebooting it by pressing Home+Power, and I actually see a little flicker - like it's trying to kick over. It had been taking a really long time to charge lately, but once it's charged, the battery seems to hold it just fine. When I get home, I plugged it into a wall charger thinking it just needed more juice. I left it on there for at least a solid hour. On the way home, I plugged it into my Griffin iTrip to charge it, and I got nothing - no red battery, no screen flicker. I went camping recently, and of course my battery drained completely about a day and half in.
