10 Steps to Maximize the SPH-m900Tips

  1. Sprint Samsung SPH-m900 is really a great phone, but is not a perfect phone. The most words that the SPH-m900 users said was

    Don't turn the phone on?

    LOL, no. Condition the battery (let it run dead, and I mean dead dead. Then recharge over night to top off the charge).

    Most people that complain about the battery life, are thinking that the 15% warning is the end of the battery... when actually there are several hours remaining after that 15% mark (my phone went on for 8hrs of moderate-heavy usage after the 15% warning).

    The phone has a terrible time judging the amount of charge in the battery, and by draining it all the way down, and charging it all the way back up, the phone/battery learns the extent of its own run time.

    So that's it. The #1 way to get the most out of this phone is to repeat that battery conditioning cycle for 3-4 days in a row. Doing that will make your phone last much longer above 15%.

    I would be surprised if it was possible to kill this phone in under 10hrs without intentionally doing everything possible to kill it. The general consensus in the battery thread is that, under normal usage, you're likely to easily hit 12+hours of run time (several have reported 30+ hours, right now I am at about 24hrs and still going).

    Ill informed suggests that this is not coming from people with first had experience. We all know the ratings are for fantastic battery life, and clearly at least half of the users of this phone are getting that battery life. It's also clear that through some glitch in the phone, that there IS a problem somewhere actually draining the battery.

    I'll use yesterday as an example:

    I charged the phone overnight, turned off, on the home charger
    10:15 AM - I removed the phone from the charger and turned it on
    11:00 AM - phone is reporting 70% battery life
    12:00 PM - phone is reporting 50% battery life
    1:00 PM - phone is reporting 15% battery life
    3:00 PM - phone is dead, turned itself off

    I made 0 phone calls, send 4 text messages and spent about 30 seconds on the app store. GPS was off, bluetooth was off and wi-fi was off.

    Now, I understand a lot about battery conditioning. I've been a manager for RadioShack for 3 1/2 years, and I'm not one of the dumb ones who can't answer technical questions. I know fully draining and fully charging is the best way to go, and I've done that.

    Clearly there are methods to get good battery life when it starts off bad on this phone. But coming from someone who's owned a dozen phones and sold thousands, I know that you shouldn't have to spend a week conditioning your battery to make it useful.

    The list you published is very informative....thanks! However, I didn't buy the phone just to have to turn off the features I bought it for in the first place!!! I know...I know...turn them off unless I use them. The thing is I paid good money for this phone (as I'm sure everyone else did), so I believe it's the manufacturers responsibility to pair the phone with an appropriate battery that can handle the load.

    Critical - although I agree with your assessment as to charging and discharging batteries, here is some additonal information concerning the the Li-Ion battery that comes with the phone. I submit this quote from Battery Life.com...

    "A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.

    Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate.


    Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory.

    Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.

    If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge."

    I've tried to keep to this mantra since I started using Li-Ion batteries and it has always worked for me.

    That being said....Samsung needs to provide the consumer with a robust battery that will handle the workload.

    Sorry this was so long folks!

    Well, if you're right. Then ignorance is the correct word, I just didn't want to come across as insulting. But you're right, it is not ill-informed, it is simple ignorance.

    On another note, it does sound like you may have a bad battery. But you already know that.

    @Rugby, Initially, it has generally been proven by the people in this forum, that conditioning the battery does increase fuel gauge accuracy, to a point. I'm not saying that you should fully discharge and recharge your phone for as long as you own it. I am saying that you should do it 3 or 4 times to get the gauge to read correctly. Give it a shot then let me know if it still can't handle the work load.

    The info the op posted is straight from Samsung's website. Pretty useless if you ask me, if you go into some of the faq's for the moment on sammy's site you will quickly realize its a lot of generic information, and nothing too specific.

    The thread is good, even if the OP's intentions are a bit dubios.

    I have studied Lithium battery life and care for sometime, and here is a great guide that explains some of it in detail:

    BatteryCare - Proper laptop battery usage guide

    Even though it refers to laptop lithiums, the concepts still apply to cellphones.

    Folks this user is just posting to promote his own webpage.

    Even if his page were to be informative, his motives for posting these links are ulterior to actually helping anyone. He has been warned about doing this by another moderator.

    Couple of things here, from experience. You wouldn't happen to spend time in a fringe 3g area would you? Switching back and forth from 3g is a huge energy drain. We live in a fringe zone and have a Airave for calls. The Airave doesn't cover data. I use wifi at home but if I leave mobile data on, my battery will last maybe 5 hours untouched. Turn mobile data off and I'll get more than 3x that and wifi is still on. Also, have you tried getting your battery swapped? My wife's Pre got horrible battery life. I got the battery replaced free from a Sprint repair center and the new one has almost double the capacity. No conditioning issue, just 2 batteries at opposite ends of what is probably considered acceptable (if they're even tested, that is). FWIW, I used a 3 battery rotation with my Touch Pro, always carrying a spare and having 1 in the charger. I rarely made it through the day with 1 battery and occasionally completely drained 2. So far, the Moment has always made it through a complete day on one charge.

    My phone lasts 12 hours of texting, browsing, etc. after I did this trick. So, I do agree with you. =) :)

    Woooow, ignore that earlier post:eek:
    Thank you, but that was prior to the CL14 up and not at all necessary anymore IMO.
