Why the right first charge is so important for Xiaomi 5
You just unpacked your new Xiaomi Mi 5, the 2016 flagship that still holds true today with the powerful Snapdragon 820 processor and 3GB of RAM. But few people know that charging it up to 20 percent of battery life depends on it, because lithium polymer batteries (namely the Li-Po 3000mAh installed in this model) have what's called "memory effect" in the initial phase of operation.
Xiaomi is not accidentally silent about the nuances of the first charge in the official instructions. In 2016, the company's engineers tested different scenarios and found that if you properly "swing" the battery in the first 3 cycles, its capacity in 2 years will degrade by only 10-12%, not by 25-30%, as in chaotic charging. We analyzed the technical documentation Qualcomm (Snapdragon 820 chipset supports advanced power management algorithms) and the experience of users from the 4PDA forum to draw up-to-date instructions.
It is important to understand that Xiaomi Mi 5 is not a modern smartphone with a smart MIUI Battery Optimization system. There is no adaptive charging control, so all the manipulations fall on the shoulders of the user. If you want to have the phone in 3 years to hold at least 60% of the charge from the original (rather than turning into a one-day one), follow our recommendations.
Myths about the first charge: what really hurts the battery Xiaomi 5
There is a lot of conflicting information on how to charge a new smartphone on the Internet, and we will examine the most common myths that are relevant to the Xiaomi Mi 5:
- 🔋 "You need to completely discharge, and then charge on 100% Three times in a row – this advice is relevant for nickel metal hydride (Ni-MH) batteries 90-For Xiaomi lithium polymer batteries 5 deep- discharge (0%) — the direct path to shortening the service life 15-20%.
- ⚡ "Charging only with the original charger is partly correct, but not critical. 5V/2A (or 9V/1.67A Supported by Quick Charge 3.0). It will even fit a charger from Xiaomi Mi 6 or Redmi Note 4.
- 📵 "You can't use your phone while charging, it's not. Modern power controllers (including the Snapdragon 820) safely distribute the load. Another thing is that heavy use (games, videos) can heat a battery above 40.°C, that's already bad.
- 🔄 "You have to calibrate the battery once a month, which is meaningless for the Xiaomi Mi 5, and you only need to calibrate if the system is not correctly displaying the percentage of charge (for example, jumping from 30% to 1.
The most dangerous myth is that the first charge must be done for 12 hours. This is a relic of the era of nickel batteries. For the Xiaomi Mi 5, recharging over 100% (when the phone is on charge for hours) leads to microdamage of the anode, which reduces battery life by 5-7% per case. Modern smartphones automatically turn off power when they reach 100%, but if you leave it connected, the cycle of “discharge to 99% → recharge to 100%” begins, which is the main cause of degradation.
Step-by-step: how to charge Xiaomi Mi 5 for the first time
First-charging algorithm for Xiaomi Mi 5 We recommend a three-step cycle that will help stabilize the chemical processes in the battery (18-25°C).
- Step 1: Primary charging to 80% Connect your phone to the original (or compatible) charger. Wait until the charge level reaches 80%, then turn off the cable. Don't push it to 100%! This is because at high voltage (>4.2V) it accelerates the formation of dendrites - microscopic "needles" that can eventually penetrate the separator inside the battery.
- Step 2: Discharge to 20% Use the phone normally until the charge drops to 20-25%. Avoid full discharge! If the phone turns off on its own, it will put additional strain on the power controller. Optimally, put a reminder on 25%.
- Step 3: Recycle to 100% Now you can charge your phone to 100%. After you reach the maximum, keep it charging for another 30-40 minutes — that's enough time to smooth out the chemical processes in the battery cells. Don't leave it overnight!
Repeat this cycle 2 more times (total 3 full cycles), then you can switch to normal charging mode.
☑️ First charging Xiaomi Mi 5
⚠️ Note: If you bought a Xiaomi Mi 5 b/d, don’t do this! For used phones, the first charge of this scheme can worsen the battery condition.
Optimal settings Xiaomi Mi 5 to extend the life of the battery
Even after the correct first charge, the Xiaomi Mi 5 battery will degrade if you don’t optimize your system settings.
| Setting up | Recommended value | Why is it important? |
|---|---|---|
| Settings → Battery → Power Mode | Saving energy | Limits background activity of applications, reducing battery heat |
| Settings → Screen → Brightness | Autobrightness (max. 60%) | AMOLED-screen Mi 5 consumes up to 30% of the charge on backlight |
| Settings → Applications → Auto Launch | Disable for everyone except messengers | Background processes drain the battery even in standby mode |
| Settings → Wireless Networks → Wi-Fi/4G | Disable inactivity | Snapdragon X12 LTE module consumes a lot of power in network search mode |
Pay special attention to temperature. Xiaomi Mi 5 is prone to overheating due to its compact body and powerful processor.°C during charging:
- 🔌 Remove the case (especially silicone – it retains heat).
- 📴 Disable all background processes through Settings → Battery → Use of the.
- ❄️ Move your phone to a cool place (but not to the refrigerator!).
💡
If the Xiaomi Mi 5 battery is running out quickly, check the battery status through the engineering menu: type ##4636## → “Battery Information.” Health should show good. If it is unknown or dead, it is time to change the battery.
What to charge Xiaomi Mi 5: the choice of charger and cable
The original Xiaomi Mi 5 kit includes a power supply with 5V/2A (10W) or 9V/1.67A (15W) performance with Quick Charge 3.0 support. However, not everyone knows that you can use other chargers - the main thing is that they meet several criteria:
- ⚡ Power: minimum 10W (5V/2A). Less - will be slow charging, more - not scary (the phone will take only the right current).
- 🔌 Protocol: Quick Charge Support 2.0/3.0 or USB Power Delivery (for fast charging).
- 📶 Cable: only with support USB Type-C 2.0 (thin cheap cables can't handle current) >1.5A).
Here is a list of compatible chargers (checked by Mi 5 users):
- 🔹 Original blocks from Xiaomi Mi 6/8/9, Redmi Note 5/7.
- 🔹 Anker PowerPort Chargers+ 1 (18W, Quick Charge 3.0).
- 🔹 Baseus or Ugreen power supplies with support PD 18W.
- 🔹 Car chargers with exit 5V/2.4A (For example, Xiaomi Car Charger Pro).
We strongly recommend not using:
- 🚫 "Non-Nauime chargers with AliExpress without certification (can give unstable voltage).
- 🚫 Chargers from old phones (Xiaomi Mi) 3/4), Not that you can support Quick Charge.
- 🚫 Damaged cables with bare wires or rubbed insulation.
⚠️ Note: If you use wireless charging (via a Qi adapter), note that this method is 30% less efficient than wired charging, which means that the battery will heat up more and the charging-discharge cycle will pass faster. For Xiaomi Mi 5, wireless charging is not recommended for permanent use.
How often to charge Xiaomi Mi 5 for maximum battery life
The optimal charging mode for the Xiaomi Mi 5 is to keep the battery level in the range of 20-80%.
- 📊 Primary 100% The voltage on the battery cells reaches 4.2-4.3V, which speeds up oxidation processes.
- 📉 Primary 0% (or <10%) internal resistance increases, which leads to irreversible loss of capacity.
- 🔄 Frequent microcycles (e.g., with 80% before 100%) cause more harm than 1 full-cycle (0-100%).
A practical tip: charge your phone when the charge drops to 20-30%, and disconnect from the network by 70-80%. If you need 100% (for example, before a long trip), do this:
- Charge to 80%.
- Turn off the charging, wait 10-15 minutes (let the battery calm down).
- Reconnect and wait for 100%.
You can use apps like AccuBattery (available on Google Play) to automate the process, and it tracks charging cycles and warns you when to turn off power, for example, you can set a 75% notification:
How to set up AccuBattery for Xiaomi Mi 5
Another nuance: Xiaomi Mi 5 I don't like to charge constantly from a powerbank or a laptop, if you're working on a computer and the phone is connected to a computer. USB-port, the battery will slowly charge-discharge in the range 90-100%, It's very harmful. It's better to use the uninterruptible (UPS) or disconnect the cable when it reaches 80%.
💡
The perfect charging schedule for Xiaomi Mi 5: 20% → 80% → 20% → 80%. Full cycle 0-100% allow no more than 1 time per month for calibration of the controller.
What to do if the Xiaomi Mi 5 battery is already worn out
If your Xiaomi Mi 5 was initially a day and now runs out in 4-5 hours, chances are your battery capacity has dropped below 60% of its original capacity.
- Diagnostics: Install the AIDA64 app and go to the Battery section. Capacity should be close to 3000 mAh. If there are 1500-2000 mAh, the battery is critically worn.
- Calibration (if capacity is normal, but percentages are jumping): 1. Fully discharge the phone before turning off. 2. Connect to charging and wait 100% (don't turn on!) 3. Disable, then turn on and check the level - it can show 90-95%. 4. Recharge to 100% when on.
- Battery replacement: Original battery for Xiaomi Mi 5 articulate MBP040. Cost - about 1500-2000 It is better to change in the service center, as it is required: 🔧 Remove the back cover (glued, risk of damaging the fingerprint plume). 🔋 Disconnect the battery (it is glued to a double-sided scotch). 📱 Reconnect the plumes without damage.
After replacing the battery, make sure to do the first charge (3 cycles 80%-20%-100%), as described above, which will help the new battery "get lost" to the power controller.
⚠️ Warning: If the phone doesn’t turn on after the battery is replaced or shows 0% despite being charged, check: 🔌 Correct connection of the battery plume (it should click). 📱 The state of contacts on the motherboard (not bent, not oxidized). 🔋 Battery compatibility (it should be marked Xiaomi) MBP040 3.8V).
