    Yow folks! I was now confused on how to really extend my battery life. Yeah I did customizing my settings and have followed the tips and tricks on improving battery life, but what's bothering me is that the first tip is to "FULLY CHARGE YOUR BATTERY ALWAYS"

    We know that Lumia 1320 has a 3400 mAh Lithium-Ion battery. And since it's non-removable, we wanted to last it's battery performance long.

    As I do research on how to extend battery life, I found this information from google. That Lithium-Ion batteries must be charged at 20% and must only reach 80% and the trick is, once in a month you must decalibrate your battery by draining it to 0 and charging it to 100%.

    So what will I follow?
    - Fully Charge the Battery always

    Or

    - Charge the phone when it turns 20% and unplug when it reaches 80%?

    Answers will be appreciated.
    Thanks

    Current Lithium-based batteries undergo irreversible chemical damage due to the "stress" it experiences as a result of high charge level differences it undergoes, i.e. by charging it fully, then discharging it by around 80% and then charging it fully again. This is the reason why most users are advised (if properly) to maintain the battery charge between 50-80% (effectively reducing the stress by limiting the charge difference to 30%).

    My advise would be to keep the phone charged as much as you can, avoiding huge charge drops and gains. By this I mean that you should avoid dropping the charge by greater than 50% straight (i.e. 50% discharge or 50% charge at one time).

    In addition to these, I think that the re-calibration the battery "does" after being "fully*" discharged is for the circuitry to adapt to the damage this "full" drain has done. Hence, I have never attempted to calibrate the battery in this manner.

    *- This doesn't really happen; internal battery circuitry is designed to "tell" the phone that is has "0%" charge once it the actual charge reaches the minimum critical limit (which is above 0%, maybe 10%), beyond which considerable chemical damage will be done which could render the battery useless.:

    So you haven't done decalibrating your phone even once?

    So you're tellling me that I must stick with 20% - 80% or advisable 40% - 80%? Or should I follow your post 50% - 100%? Lil confused about that hahaha.

    By the way how's your phone's experience?

    I'm a heavy user of 1320, when its fully charged then non stop surfing the net through wifi, it only lasts 6-7 hours. I guess it's a bad performance for a 3400 mAh battery. I really wanted to last long my battery and to extend its battery life. Hope you can help me with this matter. Thanks.

    I've attempted to re-calibrate a different Lithium-based battery before; using a battery-monitoring software, what the "full-discharge" process did was to increase "battery wear", effectively decreasing the capacity of my battery. This will trigger the "re-calibration" to adapt to the new available capacity. For example, if the original capacity was 100 (50 is 50%, and so on), then I attempt to re-calibrate by full discharge, I get a battery wear of 10. That means that there's 90 left of the capacity, where 45 is the new 50%. If I do it again and get an additional of 20 battery wear, leaving only 70 available capacity, the new 50% would be 35 capacity. And so on...

    I suggest you maintain your phone above 50%, 50-80% is better but 50-100% is also fine especially if you don't want to charge your phone frequently.

    I have an L1020 with a battery capacity that's less than your phone. With normal use (chats, sms, calls), I just need to charge my phone every 5-7 hours (without dropping below 50%). But when I take a lot of photos, I would need to charge my phone just after 2 hours (also without dropping below 50%).

    Some of the ways you can extend the cycle time of your battery (time between battery charge sessions) is to reduce the screen brightness, use WiFi for internet, turn of 4G (use 3G instead), disable unnecessary background apps, disable location services, disable haptic feedback and disable phone vibration. Disable as much as you can without limiting your phone's usability - depending on your personal preference.

    Yeah I've done disabling all the settings that aren't frequently used.

    So you're strongly suggesting me to charge my phone when it drops 50 to 80%? Or 50% to 100? I guess the 50 - 80% is a mess to me cause Im a heavy user. I do lots of stuffs (wifi on) when Im bored. And oftenly im bored haha when I was at home.

    Btw, do you think a 6 hours straight of surfjng the net is a good performance for a 3400 mAh battery?

    Your answers appreciated. Thanks

    Keeping your battery between 20-80% is the stupidest thing I've ever heard. This means you will always use max 60% percent of your battery time, which is equal to way less hours of battery life than you would normally enjoy. You freakin miss hours of battery life it could give you. You are just torturing yourself.
    Let's say charging your phone to 100% 2 years long, might drop its battery time to 70-80%, it is still more than the 60% you would torture yourself with each day.
    Why the **** would you do that?
    Just freakin charge your battery fully every time and don't let the battery die more than once a month.

    Cause when I do research how lithium-ion battery must take care of to last its best performance is to not let it down to 20% and just charge it to 80% then once in a month drain it to 0 then charge fully to 100%. Do some research too about lithium-ion batteries so you would understand what im saying.

    There's a misconception about batteries. Batteries are not supposed to be the primary power source of a device, but rather a secondary back-up power source, just like the UPS or in-house generators. It just so happened that smart phones are "mobile", thus needing a reliable mobile temporary power supply in lieu of an outlet. But then again, don't cars and airplanes have their batteries almost constantly charged by the engine? (Yes, I know these have wet cell batteries as opposed to what mobile phones have.)

    True, not using the entire 100% of a battery capacity sounds ridiculous. But consider, if you had $100,000 would you consume all of it in one sweep? A wise man won't - he'd make it last. He would invest it in something little by little, replenishing it with the proceeds of his investment.

    Frequently subjecting your battery to huge charge differences will dramatically shorten battery lifetime (serviceable life, not battery charge).

    As much as you can, charge your battery within 50-100%, better if 50-80%. Only when you don't have access to a power supply may you go beyond this recommended range - if you don't want to keep replacing your battery which is definitely a hassle.

    I don't care what you are. I also might be something..

    The fact of the practical matter is the following:

    The whole argument is about having as much battery life as possible each day during the time you enjoy your phone, which is probably 2 years.

    If you can charge a phone all the time and keep it between 50-100% you are not the type of person that needs any form of long buttery life on the go. Because you are continuously charging it and able to do so. For what purpose? You are never enjoying the fruits!! So you have a decent battery life in 2-3 years? This is hilarious because these 2-3 years you are not using any advantage of long battery life. You have to enjoy your phone today and the first 1,5-2 years.

    I have never ever had a battery in a phone that didn't serve me 2 years with normal charging. Yes maybe it has a little less battery life at the end of 2 years, but I have fully enjoyed freedom of obsessive battery care for 2 years long. And even if I have less battery life at the end of 2 years I still have a lot more battery life than you have on day one using your device if you are scared to use more than 50%.
    The comparison is simple. I rather have an average of around 85% of battery live per day over 2 years, than having about 50% of battery live per day over 3-4 years.

    Your advice for keeping a battery healthy is useful if you want to have the battery live as long as possible, lets say 3-5 years but it is impractical as hell and you are not using any of the pleasures a large capacity battery could give you during your time of use.

    So unless you're planning to use your phone longer than 3 years your advice is impractical, illogical and stupid.

    My friend, go back to Kurt's question. Does your method "extend" battery life? I don't think so. You're maximizing your battery on a daily basis, but it does NOT extend it's service life at all - not one bit.

    Also, I never said that your advice was illogical or stupid - in fact, I appreciated the discourse we were having, until I saw your first three words and last four words. Unlike you, I care; that's why I spend time figuring out what the problem is and then freely give my best insight rather than ridicule someone else's. You may be a Nobel Prize Laureate - I don't know - but irony begins in calling someone else stupid.

    I hope our friend Kurt and anyone else reading this would find some useful information from the insights we've shared.

    - Does a 6 hours straight of surfing the net through wifi a good performance for a 3400 mAh bettery? I do more facebook, youtube and watching anime/movie.

    I haven't tried using my 2,000mAh-battery that long, but based on what I've read about the L1320 in many reviews it seems that your phone should be able to last that long. You may refer to this review where all of the battery tests lasted longer than 6 hours. You could, of course, verify if the data they presented is accurate.

    When i initially got my Lumia 1320, Batter Sense would report 36hrs on a single charge.. After setting up my apps etc, i realize now that at full charge, Battery Sense reports 23hrs. I've disabled Glance, tap to wake, adjusted screen brightness, disable vibrations for all but a 2 or 3 apps, dialed back some eye candy etc and and disabled background tasks for apps I don't use. I expect a battery hit as I loaded up my apps..but not that much. . I'm sorta pissed about this battery stats.. Will fully discharge and charge to 100 and test.

    Al those tips are good ones, nothing wrong with it.
    But.....................
    Yes i know, always a but.

    But why buying a macnificent piece of hardware and use the half of its potential just because your afraid of losing power.
    Why not enjoying it the way it is ment to be.
    You do you self short by not doing so.
    It has to be very strange wenn there is never a possibilty to charge that thing.
    Okay i can think of situations when its not possible, well like in the real world...**** happends.
    When its coming critical than you can always think about shutting some services down.
    My phony runs three days at normal use ( not a gamer )
    When i am at home it last a full day by using it to the max.

    My standart setting is No data ( prepaid ) Wifi always on just like Gps
    Bluetooth is something i never use, so no loss when its off.
    Most of my apps are running free and happy in the background.
    The only thing i have set on minimum sync is my mailbox,
    i am a big boy so i dont need WP to remind me of my mail.

    So turn the switch and enjoy, when its empty charge it.

    Realy,
    you spend a couple of hundred dollars/euro's or roebels for a phone and the next thing you do is castrate the poor thing.

    Yes it's good. 5-7 hours of screen time (surfing the web, playing some games, music, videos). 2+ days standby (minimal usage) with cortana (Location services) and cell data on. I thought my battery was going bad.
