How to charge a phone battery properly: Battery care tips & tricks

How often should you charge a phone's battery, and will charging it to 100 percent reduce its lifespan? We round up the best battery care tips and tricks.
Batteries are one of tech’s most boring subjects… until your phone, tablet or laptop dies.




While most of us live in fear of a fading phone battery when we’re out and about, we don’t worry too much about that battery’s eventual lifespan (probably between three and five years). But there are ways to keep your battery in tip-top shape for a long and fruitful life.
Batteries do not enjoy eternal life. Most smartphone manufacturers say their devices rate their batteries at 300-500 cycles.
Apple claims that its laptop batteries reach 80 percent of their original capacity after 1,000 charges.
After this point batteries aren’t able to hold as much electricity and will power your device for increasingly shorter periods of time. See: Best smartphones
So here’s some tips to extend your battery’s lifespan, be that in an iPhone, Android phone, Windows phone, tablet, or laptop.
The big questions about how to re-charge a battery is whether you should let it run to zero before re-charging to 100%. One reason why people are unsure is something they’ve heard of called the battery “memory effect”.

What is battery memory effect?
Battery memory effect is about batteries remembering remaining charge if you don’t let them go all the way to zero too often. So a battery frequently charged from 20% to 80% might ‘forget’ about the 40% that’s left uncharged (0-20% and 80-100%).

Sounds crazy but that’s sort of true - but only for older nickel-based (NiMH and NiCd) batteries, not the lithium-ion batteries in your phone.
Lithium-ion (Li-ion) batteries don’t suffer the memory effect so you almost need to do the opposite: charge them often but not all the way throughout the day, and don’t let them drop to zero.

Don’t charge your phone battery from zero to 100%
The rule with Li-ion batteries is to keep them 50% or more most of the time. When it drops below 50% top it up a little if you can. A little a few times a day seems to be the optimum to aim for.
But don’t charge it all the way to 100%. It won’t be fatal to your battery if you do a full recharge - most of us are forced to do this every now and again in emergencies. But constantly doing a full recharge will shorten the battery’s lifespan.
So a good range to aim for when charging a Li-ion battery is from about 40% to 80% in one go. Try not to let the battery drop below 20%.




When should I do a full battery charge?
Experts recommend that you do a full zero to 100% battery recharge (a "charge cycle") maybe once a month only. This recalibrates the battery - a bit like restarting your computer, or, for humans, going on holiday! The same goes for laptops, by the way.

Should I charge my phone overnight?
Most modern smartphones are clever enough to stop charging when full, so there isn't a great risk in leaving your phone charging overnight. But some experts recommend you remove the phone from a case if charging for a long time, as a case could lead to over heating - which Lithium-ion batteries do not like (see below).

Should I use fast battery charging?
Many Android phones have a feature that allows for fast charging, often referred to as Qualcomm Quick Charge or, in Samsung's case, Adaptive Fast Charging.
These phones have special code usually located in a chip known as the Power Management IC (PMIC) that communicates with the charger you are using and requests that it send power at a higher voltage.
The iPhone 6 doesn’t feature fast charging, but its Qualcomm PMIC is smart enough to recognise when you use a higher-amp charger (like the one you get with the iPad), and that’s a good thing because fast charging will heat up that Li-ion battery and cause it increased wear and tear.
For the same reason, you should never leave your phone in a hot car, on the beach or next to the oven. A hot battery will suffer long-term effects on its lifespan. And so will a super-cold one, so don’t leave your device in the freezer or out in the snow.
If you can, switch off fast charging on your Android phone.

Can I use any charger?
Where possible use the charger that came with your phone, as it is sure to have the correct rating. Or make sure that a third-party charger is approved by your phone's manufacturer. Cheap alternatives from Amazon or eBay may harm your phone, and there have been several reported cases of cheap chargers actually catching on fire.

Storing battery tips
Don’t leave a Li-ion battery li-ing around too long at 0%. Try to leave it at around 40-50%.
These batteries drain at about 5-10% a month when not in use. If you let the battery discharge completely and leave it uncharged for a long period of time it may eventually become incapable of holding a charge at all (that’s properly dead).
It’s unlikely you’ll leave your smartphone lying in a drawer for very long, but some people do leave their laptop, battery packs or spare batteries unused for long periods of time. So try to keep them all at least half charged.

Common Problems About Power Banks Like Us on Facebook 1. Powerbank unable to charge my tablet? a) Powerbank with 2A output to charge tablets. While some tablets can accept lower input (1A or 1.5A), the charging is slower and sometimes can only be charged when the tablet is in sleep mode.
b) Some tablet is cables might not be compatible with power bank due to different cable chipset design. For Samsung Galaxy Tab in particular, we recommend using the cable and connector meant for power bank (comes with some power banks.




2. Powerbank battery drained off very fast? a) Generally, a well maintained powerbank can retain up to 80-90% of its original capacity. Please check your device (phone/ tablet) original battery capacity and the powerbank capacity. Please also see answer 1.a. above.
b) The number of times a powerbank can charge your device very much depends on the capacity of both the powerbank and the device. Examples of calculation shown in answer 2 above.
c) Please do not attach cables …
Dos and Don’ts When You Use a Power Bank  Like Us on Facebook Modern gadgets are power hungry. Our increasingly busy lives mean a dead battery can leave you disconnected from life, work, and your daily routine. Portable chargers and power banks will keep you from getting stranded when you’re on the go and without a convenient charging source. They are ideal for recharging your smartphones and similar devices wherever you are when you find yourself low on power.


As with all electrical and electronic devices, it’s important to treat them with respect and care to ensure they continue to work properly and safely.
With this in mind, we advise you to think about some general Dos and Don’ts to help keep you safe when using power banks and portable chargers:




1. Do use the power pack only for its intended use. E.g. to recharge your mobile phone or other USB powered mobile devices. 2. Do keep away from heat sources and liquids - direct sunlight, humidity or water. 3. Do only use connecting cables prov…
How to make your phone's battery last longer
Fed up with charging your phone every night? We offer some simple tips and tricks you can use to make your phone's battery last longer, plus point out the battery saving myths that won't help you at all.

Even in 2017, it's tough to go much longer than 24 hours without charging your smartphone. Better battery technology simply hasn't arrived yet, which means it's down to software and settings to eke out the limited power for as long as possible.
Unfortunately, you're never going to get a week's use out of a smartphone because of those big, bright screens along with Wi-Fi, Bluetooth, GPS and 4G. However, by following our advice and making a few changes to your phone's settings (and maybe even changing the way you use your phone) you should be able to extend its battery life by a good chunk.
What we're not going to suggest here is to use your phone less. Our aim is to show you how to reduce your handset'…
