10 Ways to Make Your Cell Phone Battery Last Longer!It’s no secret that cell phone batteries typically suck, sometimes not even lasting us until we get home in the evening. What’s the secret to good battery life? The general rule of thumb is that if your phone is doing anything, your battery power is being drained. And if you’re doing something fun on your phone, you can bet your battery meter will be running low shortly. This means photos, games, and web surfing will all impair your battery’s performance significantly more than regular use. So what are some steps you can take to maximize your battery life without sacrificing the fun? Read on for 10 things you can do to increase your phone’s battery life:

  1. Turn off all off all unnecessary sounds (keytones, alerts). One of my biggest pet peeves is how most phones these days come with keytones on. Do people really like hearing their phone beep, strum a musical note, or chime every time they press a button? You might like it, but ask your neighbor. Plus, turning these off will save you a good amount of battery juice. Think of all of the processing it must take to load up those midis (or whatever they are) when you touch a key – plus, they’re annoying.
  2. Use either a ringer or vibrate, but not both. I understand if you’re in a concert or loud party you want to increase your chance of actually realizing your phone is ringing, but other than that, pick one or the other. There’s no need to have your ringer all the way to the point where it has both the sound and vibrate alerts active, so I would recommend against it. I personally have my phone on vibrate at all times, regardless of where I am. If you’re worried about not hearing your phone when it’s on vibrate, put it on a table and I promise you’ll hear it. Or better yet, put it in a dish full of coins!
  3. Decrease your screen’s brightness to 50%. Go to the settings menu of your phone and change the LCD brightness. At first, the screen will look dark, but once your eyes have adjusted to it, you’ll forget about it. The LCD screen on your phone is one of the biggest (if not THE biggest) power hogs on your phone. So turn it down, and you’re on your way to a lengthier battery life.
  4. Turn your backlight setting down. Most phones these days will allow you to adjust the amount of time your backlight stays on once you’ve stopped touching buttons. The default length on most phones is probably around 15-30 seconds, but there are settings that are much lower. I would suggest turning this down to 3-5 seconds to increase your battery life. If it starts annoying you, then just crank it back up. Note: Mine backlight is set to go off after 5 seconds and it doesn’t bother me at all.
  5. Turn off Bluetooth when you’re not using it. This can be an easy one to forget about if you’re often switching between using a Bluetooth headset, and the phone’s ear piece. Turning the Bluetooth off when you’re not using it will save your phone from having to go out and check if the headset is there every few seconds. Any type of transmission will weigh-down your battery life, so if you use infrared, turn that off when you’re not using it as well.
  6. Close applications when you’re not using them. This one only affects those of us that have smartphones. Why do you need to keep that game on pause when you’re not using it? Or pocket Excel open? Just save and close them and you’ll minimize the amount of battery waste.
  7. Keep your phone in cool climates. I know most of the time you won’t have a choice where to keep your phone – since it goes with you at all times. But when you do have a choice – such as when you’re at home – don’t put your phone on the hot stove, or on your super hot MacBook Pro or anything like that. Also, don’t keep your phone in a hot car. If you have extra batteries for your phone, go ahead and store those in the refrigerator – but make sure not to freeze them. BatteryUniversity recomments storing them at a 40% charge for best results.
  8. When you’re phone is done charging, unplug it! There’s a common myth that you can over-charge your battery if you leave it plugged in. According to BatteryUniversity, “Once the battery is fully charged, no further charge is applied.” So if no further charge is applied, then why do you need to unplug your phone? You want to protect your battery from heat, that’s why. When the phone is running off of AC for a long time, extended heat may hurt the battery.
  9. Don’t let your battery fully discharge. If you let your battery die frequently, you’re putting extra strain on the battery. Avoid this by plugging in your phone before it dies all the way.
  10. Don’t do anything fun on your phone. I mentioned this above, but I’m serious here. If you have fun on your phone, your battery life will dramatically decrease. Accessing the web, playing games, navigating via GPS and capturing photos or video are not things to do while you’re in the middle of nowhere without a charger.

    Hm the tips is very useful to maintain our batteries

  • Cellphone batteries

    This is such a great article and I needed to read this — for some reason I seem to be always running out of charge in my cellphone. It really makes sense not to put your phone both on vibrate and ring mode — it's double the alert that's not necessary.

  • longer

    Nice tips there. Another good piece of advice is to turn the volume on the speaker down. This will work especially well if you happen to use your phone for an MP3 player.

  • Nir

    Thank you very much, now i know how to keep my Iphone alive for a longer period of time.

  • marquesb

    These tips are great – I have a LG Voyager and just turning Bluetooth and Backlights off (or down) allows my phone to run for up to a week at a time! without charge!

    Thanks for the article, guys!

  • hazport

    Thanks for the tips! I am not a power user on my phone but I definitely have times where I need it to work. I think these tips will help stretch the battery life.

  • ChrisTheFeral

    I never knew about unplugging it straight away.
    I generally have mine on vibrate all the time for two reasons, one, it works better than just a ring tone, in loud environment and two, I can't be stuffed finding a good enough ring tone 😛

    Great article


  • Ashutosh

    I need to follow #8, I just charge it and completely forget about it unless I get a phone call or something! Thank you for the tips. :)

  • Scyphe

    Sweet, number 7, 8 and 9 have never crossed my mind before, but I'll change my habits.

  • Asia G

    these are some truthful tips right here. and i been knew these, but i was interested in the details under the tips, very very useful.

  • erin

    also, if you're choosing between volume or vibrate, put it on volume but low. vibrate makes it die quicker

  • angela

    Actually, If It is a new battery you SHOULD run it down COMPLETELY the first few times and only charge it overnight. This conditions your battery so you will have more time between charges

  • Matt

    It has to be said though, with a little common sense this is all pretty obvious stuff. i've managed to keep my cell working with 0% charge for nearly 13 hours. It makes me laugh when my brother has to charge his cell every day.

    But nice job, number 7 I've never thought of, though i don't think i can keep my spares with the beer.. need to make a space

  • joe

    This is almost all coman sense

  • STOBA Battery

    Thanks for the tips! I am not your an advanced user, but certainly situations where I need to do. I think these tips will help prolong battery life.

  • olivia smith

    Thank u very much. Very informative article. Screen Backlight uses a handsome amount of power. Dimming it to its lowest possible setting will increase battery life. :)

  • Johns

    Thanks for the information. Nice work.

  • Roudy

    please respond to this: my cell always stops working then i charge it. when i turn back on it doesn't last more than 30 minutes before it turns off. please respond and thanks

  • reversecellphone

    Great list! I try and always have a charger handy so I don't have to worry about my battery going dead.

  • reverse phone

    It seems the biggest key in ensuring long battery life is waiting until the battery is completely depleted before recharging. This is tough to do when you are in a hurry!

  • Samuel

    I totally agree simply turn of the unnecessary features on your phone.

  • Jenny

    I never realized rings/vibrating and closing applications would leech so much battery power!

  • lastLonger

    I don't know that this is a relavent tip.When my battery runs out if i expose my battery under sunlight and reload it again in mobile it lasts longer for two more minutes.Try it our yourself.

  • sami

    keep your phone on the lowest volume NOT VIBRATE vibrate runs the battery down quicker

  • Thea

    I've been leaving my phone on the charger overnight, even when the battery isn't dead yet. Lately, I've noticed that my battery life lasts for a shorter period of time than it used to. Is this because of over-charging it? What should I do?

  • Alasisi

    Non smart phones have apps and multitasking as well as smart phones so its a gud idea to minimize or cancel those applications.

    Before going to bed at night, turn off your cellphone, wont need it while your asleep.

  • Capt. Obvious

    Yep, emergencies never happen in the middle of the night.

  • ???Steve

    Sorry but what good is promoting a hot phone that can do all the tricks if you cant use any of them? So basically we are being taken for fools for our money and lied to.Original author I’m sorry to say this but you have no good sense… Especially for that ringtone comment, i’m sure it’s the same for when you talk and write; nobody wants to witness you doing these two things neither.

    “if no further charge is applied, then why do you need to unplug your
    phone? You want to protect your battery from heat, that’s why.” – If your phone is getting hot while plugged in, you either have a faulty phone, bad apps running, or a charger that is not supplying correct voltage (ebay specials made in china).
    There is no reason why you can not leave your phone plugged in all night, all day, and even several days at a time. If left plugged in for months at a time, the battery may get a little stress from being full for so long with no use, however even this is less harm than many discharge and charge cycles. I have always kept my phones plugged up whenever I am near a charging cable and not one has had a battery go bad or seriously degrade before its life expectancy (3 – 4 years).

  • Greg Gustin

    There are several errors in your article. The largest and one of the most common misconceptions is that you should close apps manually or force close them to save power or processing cycles.

    Actually the opposite is true. Android is not Windows (thank God). It is an excellent memory manager on its own. In Android as in Linux unused memory is essentially wasted memory. So freeing up memory makes your device less efficient.

    When an app is not being used in Android, the system will put it in a very low power state until it’s called again. If the system needs more memory, then it will kill the process by itself. Killing an app causes MORE drain on both power and system resources because it takes way more power to restart an app from ‘cold’ than from ‘sleeping’.

    Task killers are as useless and unnecessary for Android as an antivirus program. News flash, Linux and Android cannot get viruses. Possibly malware but not a virus.

    Another inaccuracy in the article is that you should unplug chargers when full. Circuitry in modern phones manages battery charging quite well. After drawing what it needs, it will shut off charging and the ion flow drops to zero. No heat is created (or shouldn’t be. If your phone generates much heat when fully charged and plugged in, you may have a defect in your kernel.
    (as the poster below added)

    Last tip, if you’re writing a tech article that you have little knowledge or experience in, a little better research may be in order. In college, a paper like this would be a C- at best.
